production of Millimeter-Wave Modules for Communication, Energy Harvesting and Sensing
applications. Prof. Tentzeris will briefly touch up the state-of-the-art area of fully-integrated wireless sensor
modules on paper or flexible LCP and show the first ever 2D sensor integration with an RFID tag module
on paper, as well as numerous 3D and 4D multilayer paper-based and LCP-based RF/microwave structures,
that could potentially set the foundation for the truly convergent wireless sensor ad-hoc networks of the
future with enhanced cognitive intelligence and "rugged" packaging. Prof. Tentzeris will discuss issues
concerning the power sources of "near-perpetual" RF modules, including flexible miniaturized batteries as
well as power-scavenging approaches involving thermal, EM, vibration and solar energy forms. The final
step of the presentation will involve examples from mmW wearable (e.g. biomonitoring) antennas and RF
modules, as well as the first examples of the integration of inkjet-printed nanotechnology-based (e.g. CNT)
sensors on paper and organic substrates for Internet of Things (IoT), 5G and autonomous vehicles
applications. It has to be noted that the talk will review and present challenges for inkjet-printed organic
active and nonlinear devices as well as future directions in the area of environmentally-friendly ("green")
RF electronics and "smart-skin' conformal sensors.
Learning Design and Digital Resources for STEM Education
Professor Daniel Churchill The University of Hong Kong
Abstract. STEM (curriculum integration of Science, Technology, Engineering and Mathematics) is being
strongly recognized as critical for development of contemporary societies in the atmosphere of increasing
economic, scientific and technological globalization. STEM related reforms emphasize that the teaching
practices must (a) focus across the curriculum of the STEM disciplines, (b) be inquiry-, problem- and
activity-based, and (c) incorporate digital literacies. In this paper we explore learning design framework and
suitable digital resources for development of concept knowledge in STEM education. Further attention in
this paper is given to an appropriate curriculum design that can serve needs and requirements of STEM
education. Such curriculum must clearly emphasize importance of concept learning in STEM, in addition to
that, promote knowledge uses and development of digital literacies.

Environmental Monitoring as an IoT Application in Building Smart Campus of Universitas Udayana
Nyoman Putra Sastra, Dewa Made Wiharta Electrical Engineering Department
Universitas Udayana Denpasar, Indonesia
Abstract— The idea of Internet of Things as a platform in smart campus has become increasingly popular. It requires an infrastructure comprised of communication networks, sensor nodes, and gateways to connect to the Internet. Each sensor node is responsible to collect data from the surrounding environment.
This paper designs a wireless sensor network in internet of thing for environmental monitoring application. There are two scenarios design for this project. One uses EPS8266 to send data directly to the internet, and the other is to use Arduino and XBee 802.15.4 in multi hop wireless network. In the latter, data from several nodes are collected by an aggregator and send them to the gateway. The wireless communication between the nodes and aggregator is based on XBee 802.15.4 Radio. The XBee radios that connected to the nodes will act as a router, while another one that connected to the gateway act as coordinator. Arduino Wi-Fi shield with 802.11 standard is used to send the information to a web server. A web server based on Webrick with Ruby on Rails platform is built to display the measurement results.
Keywords—Arduino, IoT, environmental monitoring, WSN XBee, ESP8266
I. INTRODUCTION
With the advances on computing and wireless communication technologies, and emerging and exciting Internet of Things (IoT) network, more cities and university campuses are becoming smart, meaning that they are implementing those technologies to exchange data. The objectives of being “smart” are to simplify administration process, manage real-time access control, monitor the safety of the environment, and so on.
Environmental monitoring, as part of smart campus, is an application that describes any activities in a surrounding area to monitor the quality of an environment [1]. It is used in the assessments of any risk that may pose to human and the environment. Environmental monitoring applications typically utilize sensors to monitor the quality of air, water, and soil.
With the development of Internet of Things (IoT), most environment monitoring system is using a distributed framework based on wireless sensor network. The Internet of Things connects all objects of interest to the web, to make it accessible at any time [2].
This paper designs a prototype of wireless environmental monitoring system to upload information from array of sensors to database, to be part of our smart campus project in Universitas Udayana. This application allows us to monitor environment measurements in remote location from anywhere in real time. This system comprised of three main modules,
the sensor nodes, the wireless communication, and the web server. The sensor nodes in remote location collect information from surrounding and send data wirelessly using ESP8266 or XBee 802.15.4 RF Modules. 802.15.4 is an IEEE standard that specifies the media access control and physical layer for wireless personal area networks.
This paper is organized as follows: Section 2 reviews some related technologies involved in this work. Section 3 discusses the proposed model/architecture, and Section 4 reports the conclusions along with the proposals for future work.
II. RELATED WORKS A. Wireless Sensor Network
Wireless Sensor Network (WSN) is a network that consists of sensor nodes with an embedded processor [3]. The sensor nodes usually are spatially distributed to monitor physical or environmental conditions, such as humidity and temperature.
They work cooperatively and pass their data through the network to a center location.
When visual sensor (camera) is included, the network is referred to visual sensor network, which capable of processing images into a more useful form. With the use of camera in sensor network, one can create important applications, such as video surveillance, which sometimes includes algorithm like object tracking. There are many methods available to track object such as Kalman filter [4][5] and particle filter [6][7].
B. Internet of Things
The phrase “Internet of Things” was coined in 1999 by Kevin Ashton, to represent the concept of computers and machines with sensors, that connected to the internet [2].
Initially, the network was based on Radio Frequency ID (RFID) chips. After popularized by MIT, the IoT application grows into many different fields, such as surveillance, security, transportation, smart cities, etc.
In Internet of Things, there are connectivities between computers and other physical devices such as vehicles and buildings, embedded with sensors and network connectivity that enable the reading from sensors and actuators to be monitored from the internet. IoT connects wireless sensor network (WSN) to Internet, where the sensor nodes in WSN are regard as the “things” in IoT [8]. The IoT also allows objects to be controlled remotely and becomes the base of technologies such as smart cities and smart homes. Any
devices integrated into the Internet of Things are having the following characteristics [2]:
- The devices are located in an environment to be monitored, which has the capabilities of sending data to the internet or to other devices.
- The devices are programmable to act accordingly - The devices receive information from the internet
- The device is part of a collection of devices that can communicate with each other through other nodes in the same network
The IoT has been regarded as the third phase of information technology, after the internet and mobile communication. It would be part of the internet 3.0 or future internet [8].
C. Arduino
Arduino is an easy-to-use hardware and software based on open-source prototyping platform [9]. Originally, Arduino was created as tool for fast prototyping, aimed for students without any background in electronics and programming. Later, the Arduino board started to change to adapt to new needs and challenges. All Arduino boards (and software) are completely open-source. There are different versions of Arduino available on the market (UNO, Mega, Mini, Yún, etc.). Arduino Mega 2560, which has more resources for complex works, is chosen as based of this project [10]. Arduino Mega is a microcontroller board with ATmega 1280. This board has 128 KB flash memory (4 KB is used by bootloader), 4 KB EEPROM, and 8 KB SRAM. There are 54 pins for digital input/output (14 can be used as PWM outputs), 16 pins for analog input, and 4 UARTs available. It also has 16 MHz crystal oscillator, USB connection, power jack, ICSP header, and reset button. Arduino uses power from computer (by USB cable), AC to DC adapter, or batteries.
Arduino can extend communication via Ethernet, Wi-Fi, GPRS or XBee by using shields. Shields have the same pin location as the Arduino, so it is easy to assembly with.
Fig. 1 shows Arduino Mega connecting temperature and humidity sensor DHT11.

D. XBee
XBee is doing serial connection wirelessly. XBee modules provide wireless end point connectivity to devices with IEEE 802.15.4 networking protocol for point to multipoint or peer to peer networking [11]. XBee is designed for high throughput applications that require low latency. XBee uses the Zigbee standard, wraps it up in a small package. XBee 802.15.4 module becomes ideal device for applications that require predictable communication timing.

E. ESP8266 Wi-Fi Module
The ESP8266 Wi-Fi module is a self-contained system on a single chip with integrated TCP/IP protocol stack and microcontroller capability. It comes pre-programmed with an AT command set firmware and can be connected to Arduino to give it Wi-Fi access, as a Wi-Fi shield offer. This module has on-board processing power and storage capability to be integrated with sensors and other application specific devices through General Purpose Input Output (GPIO). The ESP8266 support APSD for VoIP application and Bluetooth co- existence interfaces. A self-calibrated RF allows it to work under any operating conditions, without any external RF parts.
The ESP8266 is a cost effective module with increasing community, with following features [12] :
- 802.11 b/g/n with Integrated TCP/IP protocol ; - Wi-Fi Direct (P2P), soft-AP ;
- Integrated TR switch, balun, power amplifier, matching network, PLLs, regulators, power management units, and low power 32-bit CPU
- +19.5dBm output power in 802.11b mode ; - 1MB Flash Memory ;
- SDIO 2.0, SPI, UART ;
- STBC, 1×1 MIMO, 2×1 MIMO ;
- Wake up and transmit packets in less than 2ms ; - Standby power consumption of less than 1.0mW.
The ESP8266 module works like an Arduino with a built- in Wi-Fi in the same chip.

III. NETWORK ARCHITECTURE
The proposed monitoring system is based on wireless sensor network for Internet of Things. The sensor nodes consist of a group of sensors that collect information, and upload them to the web server. We deploy two scenarios to build WSN-based environmental monitoring. The first one is by sending information from the sensor directly to internet through ESP8266 modules, as shown in Fig. 4.(a) and the second is by using 802.15.4 XBee modules (Fig. 4. (b)).

(b) Fig. 4. Network Designs
In second scenario, sensors are controlled by Arduino to gather information about the surounding. The information then sent by XBee modules (act as router) to another XBee that act as coordinator using IEEE standard 802.15.4.
We place a group of sensor nodes in a selected remote area, including including temperature-humidity sensor DHT11, flame sensor, microphone sound sensor, gas sensor, rain sensor and OV7670 camera (Fig. 5).
Fig. 5. Collection of sensors in this research
A. Web server
We need a web server to make information from sensors available to the internet. We use a web server using Ruby on Rails on Ubuntu with mysql database. Server spesification is described in Table 1.
TABLE 1. SERVER SPESIFICATIONS
Description Spesifications
Proccessor 6 vCPU of 12CPU 2.7999 GHz Intel Ceon X5560
Memory 14GB RAM
Storage 200 GB
OS Ubuntu Linux 14.04.4 (64 bit) Framework Ruby on Rails
Web server Webrick
The url of the web is ourthings.unud.ac.id, shown in Fig.
6. The code of the web server is provided by thingspeak [13]
Fig. 6. Ourthings web site
Currently, we are working only for the first network scenario. In this network, information from sensor is transmitted directly to web server via ESP8266. Fig. 7 displays information sent by one sensor, i.e. temperature sensor DHT11. This sensor is placed in our data center for testing purposes only.
Fig. 7. Temperature reading from DHT11
Communication between client and server uses HTTP POST and GET methods. Security is performed by two keys, WRITE and READ keys. The HTTP POST method requests a web server to accept and store data enclosed in the message. It is used when uploading data or file. The HTTP GET method is designed to retrieve data from server. Each sensor is authorized by WRITE key, which is required when data from sensor is uploaded to server. The READ key is required when we want to send data from server to other interface.
IV. CONCLUSSION AND FUTURE WORKS
The basic framework of Internet of Things in environmental monitoring application for building smart campus in Universitas Udayana has been shown. The things here are the sensors, which are controlled by ESP8266.
Information from sensors is sent to a web server via 802.11 standards. The web server makes the information gathered by sensors available to the internet. This network works only when Wi-Fi service is available. When it is required to put the sensor in a remote location, which no Wi-Fi service is available, we can deploy network in the second scenario. In this scenario, information from each sensor is communicated via 802.15.4 XBee to another XBee attached to an Arduino, where the latter should have Wi-Fi connection to make the system works. This scenario would be our next project.
