Abstract: This paper presents wireless transformer monitoring parameters. The main aim of this system is monitoring and controlling through RF module. The monitoring and control of transformer is done by using temperature sensor, microcontroller and RF transmission which is wireless communication. The three parameters of the transformer i.e voltage, current and temperature are monitored. Then send the same data to a remote location. Controller will make transmission between RF and client.

Keywords: Wireless control and Monitoring System, RF module, microcontroller, temperature sensor.
