Humidity Sensor InLine 40151

The InLine Smart Home humidity sensor is a compact wireless device that detects the presence of moisture and monitors environmental humidity levels. Designed for integration into a Wi‑Fi smart home network, the sensor sends contact signals when it detects liquids and can trigger scenarios or automation rules via the Smart Life app. Its small size and battery operation enable flexible placement in areas at risk of water exposure.
