This project is useful for agriculture automation.
The main purpose
of this project is to develop an automatic irrigation system which switches the
pump motor ON and OFF on sensing the moisture content of the soil. As we know
that the use of proper method of irrigation is very important in the field of
agriculture. The main advantage of using this technique is to decrease the
human intervention and still make certain appropriate irrigation systems.
Here in this project
we are using an 8051 series microcontroller which is programmed to receive the
input signal of varying moisture circumstance of the soil through the sensing
arrangement. This operation is obtained by configuring an op-amp as a comparator
which acts as interface between the sensing arrangement and the
microcontroller.
Once the controller receives this signal, it generates an
output that drives a relay for operating the water pump. An LCD display is also
interfaced to the microcontroller to display status of the soil and water pump.
The sensing arrangement is made by using two stiff metallic rods inserted into
the field at a distance. Connections from the metallic rods are interfaced to
the control unit.
