Product information

Description

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.

Advantages

The Humidity Sensor InLine 40151 offers wireless Wi‑Fi connectivity for easy integration with existing smart home systems, operates on a CR2 battery for simple installation without wiring, and has a compact form factor (24 mm depth, 68 mm diameter) and low weight (100 g) for unobtrusive placement. It can be linked with other smart devices to trigger automatisms and scenarios for faster response to moisture events.

Suitable for

Bathrooms and washrooms
Kitchens and under-sink areas
Basements and laundry rooms
Near water heaters, washing machines, and dishwashers
Any indoor location where early detection of leaks or high humidity is required
