The S-THT-02 temperature and humidity sensor is designed based on the RS-485 communication interface, compatible with the standard Modbus-RTU protocol, and can be connected to the Modbus network to achieve temperature and humidity measurement and monitoring. The THT-02 sensitive element uses SHT3X, a newly designed CMOSens chip, an improved capacitive humidity sensor element and a standard energy gap temperature sensor element. Its performance has been greatly improved or even exceeds the previous generation of sensors (SHT1x and SHT7x). ) Reliability
level to make its performance in high humidity environments more stable. S-THT-02 adopts the DIP switch to set the address, which avoids the need to set the address with the upper computer in advance. It is simple and convenient to maintain and replace. S-THT-02 has excellent long-term stability, low latency, low power consumption, strong resistance to chemical pollution and excellent repeatability. It is used for accurate temperature and humidity relative measurement in HVAC, communication equipment rooms, warehouse buildings, and automatic control applications. The ideal solution for humidity.
