the Water Alarm Circuit



                                       The Water Alarm Circuit






It's just a water sensor, which can be configured as an Alarm Indicator tank overflow alarm rain water leakage from aquarium water, etc. It can be powered from any supply 6VDC. Initially, when the DC power supply circuit, the red LED is off. However, it detects when the presence of water between the detection probes (s1, s2), the LED blinks at a slower pace.
