You can use this automatic water tap for washing hands without touching the tap. You can also make automatic water dispenser machine for dispensing drinking water.

This IR Sensor dispenser circuit for automatic water dispenser has been designed and manufactured by DNA Solutions, Nashik.

IR Sensor dispenser circuit works on 8 volts to 24 volts. So you can drive not just 12 Volt solenoid valve but also 24 Volt solenoid valve. The IR Sensor dispenser circuit also has on board potentiometer to set the timing for which the water is being dispensed. The timing can varied from 0.1 seconds to 5 Seconds. So even though the hand is not removed the solenoid is cut off after the set time thus saving water.

This automatic water tap is very useful in Restaurants, public places and offices.

The IR Sensor dispenser circuit can be used not only to make automatic water tap it can be used to make Automatic Hand Sanitizer Machine as well.
