Thermo-hygrosensor Renkforce RF-E0666-W wireless 433 MHz white – temperature and humidity sensor

The Renkforce RF-E0666-W thermo-hygrosensor is a compact wireless sensor that measures ambient temperature and relative humidity and transmits the data on the 433 MHz band to compatible receivers. Designed for indoor placement, the unit in white integrates unobtrusively into homes, greenhouses, storage areas and other environments where continuous monitoring of climate conditions is required. The device provides straightforward climate readings that support adjustments to heating, ventilation and humidification systems.

Advantages

This thermo-hygrosensor offers wireless transmission on 433 MHz for easy integration with matching receivers and displays. Its compact form factor allows mounting on walls or placement on flat surfaces without occupying significant space. The sensor provides reliable measurements of temperature and relative humidity across typical indoor ranges and is energy-efficient for extended battery life. The neutral white finish matches a variety of interiors.

• Home rooms and living spaces for monitoring comfort conditions
• Indoor greenhouses and plant rooms to track humidity and temperature
• Storage areas and cellars to prevent moisture-related damage
• Offices and server rooms for basic ambient monitoring

Key specifications

• Measured parameters: ambient temperature and relative humidity
• Wireless transmission frequency: 433 MHz
• Color: white
• Mounting: wall-mount or freestanding placement
• Intended environment: indoor use

How to use

Place the sensor in the desired indoor location or fix it to a wall using the provided mounting option. Ensure the unit is within range of a compatible 433 MHz receiver and that the receiver is configured to accept the sensor’s signal. Allow the sensor a short stabilization period after installation to reach ambient conditions before taking readings. Replace batteries according to the receiver or sensor indicator when signal strength or update frequency decreases.

Usage recommendations

Install the sensor away from direct heat sources, drafts, windows with strong sunlight and damp surfaces to obtain representative ambient readings. Position the device at typical breathing or plant canopy height for the most relevant temperature and humidity data. Check compatibility with your display or base unit for 433 MHz sensors prior to installation to ensure correct reception and reporting.
