Abstract: The title itself indicates that the system checks the moisture content in the soil and based on moisture content, motor will be on/off automatically. In this paper, the system divides in three nodes. The central node based on ARM7 and other two nodes are based on AVR. The heart of whole system will be central node. In each nodes, soil moisture sensor, RF module and solenoid valve are attached. By using the soil sensor, we can find, whether the soil will be dry or wet. If the soil is dry then the motor will on and if the soil is wet, motor will off. All information will be display on central node LCD. The motor will be on or off, according to particular node condition. When one node is dry then motor will be on, in that particular node, similarly, same condition will be apply for all nodes. When two nodes will dry, then two motor of that node will be on. Here, the soil sensor gives the status of moisture to the microcontroller through rf modem and this all information send to microcontroller, based on that information motor will be on or off. All information of irrigation stored in data logger in central node. The pumping motor will pump the water into the field until the field is wet. When the soil is wet, motor will off automatically. This saves the water at the same time and on the other hand the plant can get optimum level of water, so increasing productivity of crop.
