WATER SENSOR
Rs. 20.40
Water Presence Sensor with parallel exposed conducting traces. Grounded traces are interlaced with signal traces held high by a 1MΩ pull-up resistor. When water bridges a sensor trace to a ground trace, output voltage drops — detectable on Arduino digital or analog pins. Analog output 0–4.2V proportional to water contact area. Low power (<20mA).
