## Long description

The Renkforce RF-E0666-BK is a wireless thermo-hygro sensor operating on the 433 MHz band that measures ambient temperature and relative humidity. Designed as an accessory for compatible monitoring and weather stations, it transmits measured values to a receiver for remote display, logging or alarm functions. The compact black housing and battery-powered design allow flexible placement indoors or in sheltered locations to monitor microclimates, storage areas or hobby rooms.
Advantages
The sensor provides wireless transmission of temperature and humidity data at 433 MHz, enabling integration with receivers and stations that support this frequency. Its small form factor permits discreet installation in different rooms or cabinets, and battery operation eliminates the need for wiring. Measurements are suitable for climate monitoring, helping to detect moisture trends and temperature deviations early. The device is compatible with systems that accept external thermo-hygro inputs, supporting remote monitoring and automated responses from a connected receiver or station.
Suitable for
Indoor climate monitoring in living rooms, bedrooms and offices
Storage and archive monitoring to protect documents, textiles and electronics
Greenhouses, plant rooms and hobby terrariums with sheltered placement

How to use
Place the sensor in the location where you want to monitor temperature and humidity, avoiding direct sunlight, heat sources or areas with excessive condensation. Insert the required battery and follow pairing or channel selection instructions of the compatible receiver or weather station to establish a wireless link on the 433 MHz frequency. Once paired, the sensor will transmit periodic measurements to the receiver for display, recording or alarm processing. Position the sensor at a representative height and orientation for accurate ambient readings.
Usage recommendations
For reliable measurements, replace batteries before low-battery conditions occur, mount the sensor away from radiators and windows, and consult the receiver or station manual to confirm compatibility with 433 MHz external sensors. For storage-sensitive items, monitor both temperature and humidity trends and set alerts on the receiving device if supported.
