CHAPTER 1 1 INTRODUCTION
5.3 Recommendation For Future Work
There are several recommendations can be done for future work to improve the overall IoT water quality monitoring of this project. Firstly, the Arduino Nano development board can be replaced by a 16-bit low power microcontroller provided by Microchip in order to reduce the overall power consumption of the system and increase ADC accuracy as ATMega328p is a 10-bit microcontroller.
Secondly, LoRa device can also be used to replace ESP8266 as data transmission as LoRa device consume significantly less power than ESP8266 and it is able to transmit at longer range. Moreover, with bigger aquaculture farm, ESP8266 require stronger WiFi signal in order to transmit the data. Thus, LoRa device is a better choice for a larger aquaculture farm. Moreover, instead of changing to the LoRa device, ESP8266 can also use the MQTT protocol to transmit data as it is able to operate in narrowband and consume less power then HTPP protocol. However, the drawback of both of these methods is, it requires to set up a ground station to receive the data from the logging system and transmit the data to the cloud via WiFi at the ground station.
Thirdly, as the logging system collects more and more data, Artificial Intelligence can also be implemented in the cloud server in order to provide a prediction based on the water quality parameters logged into the cloud. This will
allow the aquaculture farmer to get an earlier alert before the water quality is out of range.
Lastly, more sensors can also be added to the system to monitor more parameters and more decisions can be made based on the monitored result. Sensors such as an ammonia sensor should be added to the aquaculture pond as water ammonia levels are equally important as pH to the fish.
