GSM Based Automatic irrigation Water Control System

Types of irrigation

Various types of irrigation techniques differ in how the water obtained from the source is distributed within the field. In general, the goal is to supply the entire field uniformly with water, so that each plant has the amount of water it needs, neither too much nor too little.

  • Localized irrigation[Spray Head]
  • Drip Irrigation

Lateral move (side roll, wheel line) irrigation

Manual irrigation using buckets or watering cans

Automatic, non-electric irrigation using buckets and ropes

Irrigation using stones to catch water from humid air

Dry terasses for irrigation and water distribution

This system is a remote controlled pump control system. The remote control media used is the regular GSM cell phone.

The system installed at the farm has two moisture sensors which analyze the moisture content of the soil.

When the sensors are dry, System send SMS to user which will let him know that the farm has dried up.

Then by sending a particular SMS using his phone to the system he can switch on the water pump or Valve. The pump can be switched off in the same manner. User can also set ON and OFF time.

This system, if implemented, will save a lot of time, energy and money of the farmers by automation of the job.

SYSTEM DESCRIPTION AND OPERATION

This system can be used in fields for providing them with water by switching on and off the pumps at the field using a mobile phone. For this purpose a GSM MODEM with a SIM card is to be attached to the system and placed at the farm itself. The system has moisture sensors with variable sensitivity that can detect moisture levels in the soil. Two sensors are used so that moisture in the soil can be measured at more than one place. The system gives SMS clues to the user about the moisture content and the pump status to the user.

User can send a particular format SMS to the system to turn ON and OFF the Pump or Valve and also set the ON and OFF time of Pump or Valve.

system can be divided in to smaller parts.
