Circuit diagram for smart water tap.
Water tap sensor circuit diagram.
Install the circuit on each general purpose pcb and house in a suitable cabinet.
We will use an ir sensor and a water switch to make this automatic infrared water tap.
This circuit is nothing but a water activated solid state switch s201s02 capable of driving ac mains operated loads.
This circuit works with a 9v power supply.
The ir sensor is made using 555 timer used as astable multivibrator vibrating at around 38 khz.
After this connect the common 1 of relay 1 to negative 24 v dc power and common pin of.
And another 555 timer ic is used as monostable multivibrator for tap circuit.
Sensor to relay input pin 1 and second sensor output pin to relay module input pin 2.
Connect the end of the junction 555 pin 2 and 6 to the water tap.
It remains active until you turn off the circuit by switching s1 or removing the sensor from the tap.
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.
No microcontroller is used to make this automatic infrared water tap simply place your.
Automatic infrared water tap at 5.

Possible applications for this water switch circuit.
That is when the valve is turned on it will consume.
The water sensor is inserted into the water tap.
The tap starts whenever anyone put his her hand in front of sensor which is below the water tap.
