Solar powered wireless irrigation system is perfect solution to the Indian farmer in such energy crisis.Solar
power is the best solution for the energy crises and perfect for use in irrigation systems. When the sun is hot Solar Panel will
absorb sun rays and will convertsolar energy to electrical power which is saved in to batteries. In this project the water
quantity present in agricultural soil is detected by soil moisture sensor and water level sensor for detect water level in tank.
Based on soil moisture sensor values, the water pump is switched on and off automatically. When moisture level of the soil is
dry, the soil moisture sensor will send the signal to Atmega328 to start the pump by using stored solar energy. Same time,
ZigBee processes values of sensors from Atmega328 and this values from different sensors (Soil moisture, temperature,
humidity and water level), are collected in the PC according to date and time, and periodically updates it for synchronization
for graphical user interface (GUI) by using VB software that is visual basic. The sensors values, switching of the pump i.e.,
on/off are displayed on a 16x2 LCD which is interfaced to theAtmega328.
