Design and Implementation of Autonomous Solar Powered IoT Farm Monitoring System using MQTT over Cellular Network

摘要

Modem agriculture enhances the efficiency of farming by reducing the operational cost and increasing the yield. One of the key of reducing operational cost in farming is by transforming the manual process into automatic process. Farm monitoring such as soil, irrigation and weather monitoring is the process that can be turned into automatic and remote by implementation of internet of thins (IoT). The challenge of IoT system in agriculture farming is the needs of energy and communication in remote area. Autonomous IoT system for farm monitoring is designed and implemented using energy from photovoltaic (PV) and battery. The system is designed to utilize cellular network for long range communication and using Message Queuing Telemetry Transport (MQTT) protocol for data collection. The system is designed to monitor soil, irrigation, weather and its battery state. From implementation, it shows that the system requires power of 7.31 watt and can be powered by 100 watt peak PV and 18 Ah 12 V battery.
