Indoor Temperature and Humidity Sensor with Display

The wall-mounted temperature and humidity transmitter adopts high-precision temperature/humidity sensors and digital circuits. Its multi-angle ventilation design prevents internal temperature rise from affecting measurement accuracy, and it is suitable for both wall-mounted and ceiling-mounted installation. The optional ambient light and OLED display enable more intuitive visualization of environmental comfort levels. A variety of optional colored lenses are available to match different interior decoration styles of users.
It is ideal for air conditioning systems or outdoor applications that require high measurement accuracy and fast response time for relative humidity, with a measurement range covering 0~100% RH. Typical applications include:
Commercial buildings, cinemas and office buildings
Laboratories, hospitals, electronics, pharmaceutical and food factories with purification requirements
Silk and paper manufacturing industries, chemical and storage warehouses, cold storage facilities, computer rooms, museums, greenhouses and other spaces requiring temperature and humidity measurement
