Indoor Humidity Sensor Brennenstuhl 1293910 Freestanding Wireless 3V CR2032

The Brennenstuhl 1293910 indoor humidity sensor is a freestanding wireless device for monitoring relative humidity in indoor spaces. Powered by a single 3V CR2032 battery, the compact sensor measures 36 mm in width, 11 mm in depth and 60 mm in height, allowing placement on desks, shelves or flat surfaces without wiring. The product provides continuous local sensing of ambient humidity to help maintain comfortable and healthy indoor conditions.

Advantages

The sensor’s compact freestanding design enables easy relocation and discreet placement in living rooms, bedrooms, offices or utility rooms. Battery operation with a commonly available 3V coin cell reduces installation complexity and eliminates the need for mains power or cabling. The device delivers accurate relative humidity readings suitable for routine monitoring and is compatible with standard indoor use cases where wireless, low-power sensing is required.

Suitable for

• Monitoring humidity in living rooms and bedrooms
• Use in offices, workspaces and server cabinets for basic ambient monitoring
• Placement in utility rooms, pantries and storage areas to detect moisture variations
• Portable checks of indoor humidity when moving between rooms

How to use

Insert a new CR2032 battery into the battery compartment following the polarity markings, then place the sensor on a stable, flat surface at the height and location where you want to monitor humidity. Avoid positioning the device directly next to heating vents, open windows or sources of steam to ensure representative ambient readings. Allow a short stabilization period after placement or battery replacement for the sensor to provide accurate measurements.

Usage recommendations

For reliable long-term readings, check and replace the CR2032 battery before it is depleted, and clean the sensor housing periodically with a dry cloth. Position the device away from direct sunlight and strong airflow. Use the recorded humidity information alongside ventilation and heating controls to maintain recommended indoor relative humidity ranges.
