A long maximum indoor range supports flexible placement throughout a home or small office when used with a compatible hub or receiver. The device's small footprint and straightforward functionality make it suitable for integration into automated routines that respond to humidity changes.

How to use
Place the sensor in the area where you want to monitor humidity, on a stable flat surface or mounted on a wall at typical breathing height for accurate ambient readings. Install the CR123 battery according to the polarity indicated in the battery compartment, then pair the sensor with your compatible hub or receiver following the manufacturer’s pairing procedure. Allow a short stabilization period after placement for the sensor to reach ambient temperature before relying on its readings. Check wireless connectivity and signal strength if readings are delayed or missing.
Usage recommendations
For reliable measurements, avoid placing the sensor near direct heat sources, air vents or open windows. Replace the CR123 battery promptly when low-battery alerts occur and verify placement if signal range problems appear. Use the sensor as part of a broader humidity management routine—combine regular readings with ventilation or dehumidification actions to maintain recommended indoor humidity levels.
