Wide temperature measurement range from -40 °C to +85 °C
Humidity measurement from 0 to 100 % RH
Suitable for temperature and humidity monitoring at the same time
Useful in heating, ventilation and humidity control systems
RJ11 4P4C connector allows easy connection to compatible devicesDisadvantages
Works only with compatible devices
The sensor itself does not perform a control function – it requires a compatible controller
Not suitable for use as a standalone display thermometer if it is not connected to a control systemWhere is this SONOFF sensor most commonly used?
It is most commonly used in greenhouses, garages, basements, warehouses, technical rooms, server rooms, residential premises and other places where temperature and humidity need to be monitored.
Can this sensor control heating or ventilation?
The sensor itself only measures temperature and humidity. Control requires a compatible controller, which, based on the sensor data, can turn heating, a fan, a dehumidifier or other equipment on or off.
What is the temperature measurement range?
The sensor measures temperature from -40 °C to +85 °C.
Can the sensor be used outdoors?
The sensor can measure low and high temperatures, but before using it outdoors, protection against direct moisture, rain and mechanical damage must be assessed.
