Rain Sensor


5 na zalogi



Sensor for detecting rain drops and splashing water. The sensor is made up of two parts, one sensor board and one amplifier. The sensor is made from a circuit board with interleaved traces that, when exposed to water, will start to conduct. The amplifier transforms the changes in resistance into a voltage that can be measured with a microcontroller. A trimmer is available for adjusting the sensitivity. Two simultaneous outputs provide a digital signal that is either low (no water) or high (much water) and one analog output where the voltage is dependent on the amount of water.
