iterfacing of soil moisture sensor with 8051 microcontroller
PROJECT DESCRIPTION
The title itself indicates that the system checks the moisture content in the soil based on which a pumping motor automatically pumps the water into the field. Here, we are using a soil moisture sensor. By using this sensor, we can find whether the soil is wet or dry. If it is dry, then the pumping motor will pump the water. In this system, the main controlling device is a microcontroller. Here, the soil sensor gives the status of the soil to the microcontroller, based on that the microcontroller displays the status of the soil on the LCD, and switches on or off the pumping motor through a relay.
The pumping motor pumps the water into the field by using a drip water system until the field is wet, which is continuously monitored by the microcontroller. In irrigation process, the most critical parameter of monitoring is soil, so we have to monitor the soil condition, whether the soil is dry or wet. If it is dry, then by using the pumping motor, water has to be pumped automatically. The main aim of our system presented here is to monitor the moisture content in the soil in a cultivating field. Based on the soil moisture, pumping motor will be automatically switched on or off through the relay. This saves water as well as the plants can get optimum level of water. This will increase the productivity of the crop.
In this proposed system, we use an 8051 series microcontroller which has been programmed to obtain the input signal of variable moisture condition of the soil through the sensing arrangement. This is achieved by using an op-amp as comparator which acts as interface between the sensing arrangement and the microcontroller.
The concept in the impending project can be heightened by integrating it with GPS/GSM technology, such that whenever the water pump switches on/off, an SMS is delivered to the concerned person regarding the status of the pump, enabling the user also to control the pump
