A WIRELESS IRRIGATION SYSTEM USING ZIGBEE TECHNOLOGY



A WIRELESS IRRIGATION SYSTEM USING ZIGBEE TECHNOLOGY

Abstract:



In the irrigation system we generally use induction motors where the water has to be pulled out and irrigate the plant. But it is difficult to check the availability of the water in the field all the time. So here we are considering a wireless system to monitor the condition of the plant and then if there in any insufficient amount of water in the field then the network built will check the plants status and then water level.



Normally in this field it is not possible for a person to continuously monitor the condition and the water level in the field. The water level that is in the field has to be monitored and the level of the sump has to be checked and then the motor has to work accordingly.  Here actually we are using a wireless network. That is ZIGBEE communication system. This actually monitors the humidity in the field and water level in the tank and the currents and voltage of the motor. In the field it is common to find that the current and voltage are not always the same. So that we check the current s and voltages and then if the voltages and currents are at required level then it immediately transfers the signal to the motor to switch it on. This checks not only the current and voltage values even the level of the water that is present. If the level of the water is at a sufficient level then it automatically switches on the motor.  If the water level is insufficient for that time then it instructs the motor to switch it off.
