ABSTRACT

The autonomous used to detect the three types of fault which cause damage to the motor. It is expected that this application will be comfortable for the farmers and this provides easy access of motor to a greater extent. All these control process are achieved by using a PIC microcontroller, GSM and Different interfacing and control circuits. The receiver phone receives the DTMF signal or a SMS message that is send from the user?s phone and then sends it to the DTMF decoder or the GSM modem which in turn sends the output digital signal to the microcontroller. Then the microcontroller, based on the received signal, controls the different relays connected through ULN2003 (Darlington transistor) and triggers the required appliance may be Direct on line or Star Delta. The motor is controlled by the micro controller and the present status of motor is sensed and it is automatically controlled by itself and the information is transmitted to the corresponding person through GSM network. The GSM mobile phone is used as an alternative to turn on and off the motor through a message or a missed call and also to send message to the owner about the following three faults. agriculture irrigation using GSM network. This project provides the development of mobile phone as remote control application for submersible motor pump which is used in agriculture irrigation. The motor connections depends upon its horse power, it Embedded System based submersible motor control to prevent it from over load, dry run and single GSM module SIM300 is being used in the project here. It is just like a cell phone with all the facilities of sending and receiving a message, sending and receiving calls. It has a communication that can be programmed using AT commands. The signal names for the GSM modem communication port include the following; audio input and output pins (for connecting external hands free audio devices), mute control pin, flash programming signal pins, external power pins, and receiver and transmitter pins. Then at last voltage controllers are associated over the circuit to secure the supplies from any kind of voltage variances. All the gadgets we utilize are delicate and sensitive, so protection from any kind of variances is very important.
