Water Tap Sensor Circuit Diagram

We will use an ir sensor and a water switch to make this automatic infrared water tap.

Water tap sensor circuit diagram.

The ir sensor is made using 555 timer used as astable multivibrator vibrating at around 38 khz. Automatic infrared water tap at 5. Circuit diagram for smart water tap. The complete circuit diagram for arduino based water dispenser is shown below the solenoid valve used in this project is a 12v valve with a maximum current rating of 1 2a and a continuous current rating of 700ma.

No microcontroller is used to make this automatic infrared water tap simply place your. The tap starts whenever anyone put his her hand in front of sensor which is below the water tap. It remains active until you turn off the circuit by switching s1 or removing the sensor from the tap. The water sensor is inserted into the water tap.

This circuit works with a 9v power supply. Possible applications for this water switch circuit. Learn more about using ultrasonic sensor with arduino here. Then connect the solenoid valve one wire to n c normally close part of relay 1 and another wire to no normally open part of relay 2.

That is when the valve is turned on it will consume. After this connect the common 1 of relay 1 to negative 24 v dc power and common pin of. This circuit is nothing but a water activated solid state switch s201s02 capable of driving ac mains operated loads. And another 555 timer ic is used as monostable multivibrator for tap circuit.

In this project we will make an automatic on off water tap under 5 only. Rain alarm watertap leak detector water level sensor for bathroom water heaters wetness checker for flower pots and more.
