GSM/GPRS based Pump ON/OFF System

Project code:-E77 Project Cost:- INR:- Rs.7500/- USD:- 230$

GSM/GPRS based Pump ON/OFF System

As the name suggest any pump can be switched ON or OFF by a simple miss call from mobile phone. It will only accept the call from the authorized User and not from anybody else. User can register his mobile number first time into GSM modem SIM by giving a miss call to the SIM number placed inside the GSM modem. Thereafter it will only listen to that number. User can change the registration at any time with ease. By simply connecting a jumper and calling from new number.

The project presented here is based on world’s most powerful Intel’s mcs-51 family of microcontroller Atmel AT89c20511.,since this controller has only two ports are more than enough for our project

Application area:
Mainly in agriculture. Pumps used in agriculture land located at the distant remote place

This device has the following blocks
1. GSM modem Sim 300 or Sim900 or any similar
2 Microcontroller circuit the central processor 89c2051 IC2
3. IC5 MAX 232 for RS232 level conversion
4. Driver circuit where 2 relays where two ON /OFF RELAYS will be connected.
5. Power supply circuit IC1, 7805,bridge rectifires D1-D4 Capacitor C1 , C2 and C3.
6. Feed back circuit , an op-to isolator for status SMS feed back.
