Description
This is a humidity detection sensor module for Arduino. The sensor is made from a circuit board with interleaved traces that, when exposed to water, will start to conduct. The sensor is made up of two parts, one sensor board, and one amplifier. 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. This has applications like automatic windshield wipers, smart agriculture, and home automation.
