Valerian Agustinus Sinulingga ABSTRACT

IMPLEMENTATION OF TEMPERATURE CONTROL AND MONITORING SYSTEM THROUGH IOT IN HOME GARDEN SEEDLINGS

By

Valerian Agustinus Sinulingga Erikson F.Sinaga, S.T., M.Kom., Advisor

SWISS GERMAN UNIVERSITY

The development of automation technology has spread widely from the time it is discovered to help mankind progress. In this thesis work one of the automation technology was implemented for urban farming. The home garden can control the temperature, lights, and soil moisture of the plants. This thesis work main focus is to develop a system to cool the high temperature of home garden, keep the plant healthy by giving it water and light and monitoring it via Internet. The development of this thesis project was made possible by Arduino as the controller and with Raspberry Pi for camera monitoring system. The camera it was used is raspberry pi camera module 5MP, the video will be streamed to local IP. With Internet of Things support, the monitoring for data can be streamed by using ThingSpeak, thus the Arduino will send the data to ThingSpeak website. The soil moisture, temperature and intensity of light are read by using YL-69, DHT22, and photoresistor. The garden will be giving a suitable need for the plant to grow.

Keywords: Arduino, Internet of Things, YL-69, DHT22, Photoresistor, Camera Module, ThinkSpeak
