Villages are the backbone of our nation. The farmers strive hard day and night to yield very good results in their farm. They know the entire process how to produce a farm, when to provide water to the farms etc. When it is the time to water the farms, they just stop their current works then and there and rush to the farms to start the pump sets to water the farms.
This project provides an excellent solution to this process. The farmer need not go to the farm to water his field. He can sit at his present place and start the motor on to water his field. No cabling or hardware connections are required to do this. Everything will be carried in a wireless fashion and this system is entirely an automated product. The DTMF modem performs the task of receiving the message from the mobile and sending the messages to the mobile from the controlling unit.
The modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. The DTMF modem is a wireless modem that works with a DTMF wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.
To the motor, DTMF modem with the controlling unit will be fixed. If the farmer wishes to water his field, he needs to switch on the motor. Thus, he has to send a predefined message to the modem from his mobile. The DTMF modem receives this message and intimates the same to the microcontroller. Now it is the job of the controller to switch on/ off the motor in accordance with the received message.
