About - Temperature Humidity Sensor

This compact temperature humidity sensor is designed to withstand various elements. The detachable high-strength waterproof housing protects the internal sensor from solid objects in contact with it. The transmitter can provide RS485, 0 to 5 VDC, 4 to 20 mA or 0 to 10 VDC temperature and humidity output signals. The transmitter is very suitable for temperature and humidity monitoring in public places such as industry or residential buildings. Free cloud platform. We offer two types for you to choose: humidity and temperature sensor, humidity and temperature sensor with LCD.

temperature sensor


This RS-WS-*-2D temperature and humidity sensor has a fully enclosed design with a protection level of IP65, effectively

avoiding the corrosion of the sensor module by moisture, smoke, and dust in the air. It can be used in harsh environments for a long time.

Output signal: RS485/4-20mA/0-5V/0-10V

Price: $25.2


This temperature and humidity sensor is based on the RS-WS-*-2D transmitter with an LCD display, which can directly read the current temperature and humidity values. There are four keys at the bottom to manually set the temperature and humidity calibration values, communication address, baud rate, and device password.

Output signal: RS485/4-20mA/0-5V/0-10V
