Abstracts: Aim of this design is to develope a system based on embedded microcontroller (PIC16F877A).This embedded system is use for the all the farmers in the world. This system reduces the waste of time of farmers. This system detect 3-phase supply and send message or (rind tone) to farmer to inform them the 3-phase is detected with the help of mobile phone. it can easily operate this system. We use microcontroller (PIC16F877A), GSM modem and mobile phone. It is much possible to reduce the cost of system.
