Water sensor circuit using 555 timer


Posted on Feb 7, 2014

The water sensor circuit is based on a 555 timer circuit and come common electronic components. The water sensor is made by two metal electrodes arranged very close that a drop of water (liquid) will bridge them. If the liquid ( water ) is very pure you may change the resistor value to 2. 2m ohms and if the circuit is give false alarm sensing you
