Drip Irrigation

Abstract

In the field of agriculture, use of correct methodology of irrigation is vital and it's documented that irrigation by drip is extremely economical and economical. In the typical drip irrigation system, the farmer must keep watch on irrigation timetable, that is totally different for various crops. The project makes the irrigation automated. With the utilization of low price sensors and therefore the easy electronic equipment makes this project a coffee price product, which can be bought even by a poor farmer.This project is best fitted to places wherever water is scares and must be utilized in restricted amount. Also, assemblage countries will afford this straightforward and low price resolution for irrigation and procure sensible yield on Crops. The heart of the project is that the Intel 89c51microcontroller.UART controller that will be used in this project. A 16×2 liquid crystal display is connected to the microcontroller, which displays the humidity level and ambient temperature. Three pushbuttons are provided to set the limits of humidity for switching the individual solenoid valves controlling the water flow to the field. The wetness and temperature levels square measure transmitted at regular interval to the laptop through the RS232 port for information work and analysis. The wetness sensors square measure created exploitation Al sheets and housed in simply out there materials. The aim is to use the promptly out there material to construct low price sensors. Five relays square measure controlled by the microcontroller through the high current driver IC, ULN2003. Four relays square measure provided for dominant four coil valves, which controls the flow of water to four different parts of the field. One relay is employed to shut-off the most motor that is employed to pump the water to the sector.
