This project is used for heating water using solar
power. The main parts in this project are pump, solar heater, tank, heat
sensors and controlling unit.
The tank consists of two parts. In one part, the cool water is stored. A pump pumps the cool water to the solar
heater. The water is circulated inside
the heater and gets heated. The outlet
of the solar heater is connected to the other side of the tank.
One heat sensor is connected inside the tank of the
cool water side and another sensor is connected at the outlet of the water
heater. The two sensors are connected with a microcontroller unit. The sensors
sends signal to the microcontroller unit. The if the temperature of the hot
water(outlet of the solar heater) is less than the temperature of the cool
water(in tank) ie less solar energy, the microcontroller stops the pump motor.
Other wise(If more solar energy) the microcontroller switch on the pump
motor. Thus the pump motor is operated
automatically accordingly with the solar energy. Simultaneously the user can
use both the hot water and cool water. This project is very cheap and easy to
use. Since microcontroller used, the
operations will be more efficient.
