This circuit gives out an alarm when its sensor is wetted by water. A 555 astable multivibrator is used here which gives a tone of about 1kHz upon detecting water. The sensor when wetted by water completes the circuit and makes the 555 oscillate at about 1kHz. The sensor is also shown in the circuit [...]

Get advance notice of potentially hazardous water leaks in your home or office with a system that alerts you when water buildup is detected. The Waterbug 800 8-Zone Water Sensor Alert Kit can monitor up to eight supervised or 16 non-supervised zones; four supervised sensors are included, additional WaterBug Surface Sensors are available separately. The [...]
