DC 5V Water Vapor Sensor Module Humidity Detection Board for Arduino
Water vapor sensor is a sensor that detects the presence of water using humidity measurement. It can be used to detect rain. When the sensor is placed outdoors and raindrops fall on the petal-shaped detection area, the humidity increases, and the output voltage also rises. In addition to detecting rainwater, it can also detect mist or water vapor.
