Design and Development of Remote Monitoring Solar Powered Agricultural Motor Pump Using Modbus and MQTT IOT

Global political and economic initiatives are driving the demand for alternative power sources. Solar power has been the leader amongst other renewable energy sources. In this project the solar power is used to run the agricultural motor pump. The variable frequency drive (VFD) is used as a controller for motor pump and the solar power is given as input to the VFD controller. This VFD controller will controls the motor pump operations. Along with this we are developing a Remote Monitoring System (RMS). The solar power and motor pump values are read by RMS from controller. RMS uses MODBUS communication to read the data from VFD drive, and by using the Message Queuing Telemetry Transport (MQTT) Protocol all this data is sent to web server. With the help of Global Position System (GPS) tracking we can find the installation location of the motor pump. In this Global System for Mobile Communication (GSM) is used for ON/OFF of motor pump through SMS or call. The status of the motor pump whether ON/OFF, its frequency, power, voltage, speed, controller temperature and all its real time values can be seen in web server at any time.
