Duct Temperature and Humidity Transmitter with RS485 Interface

THT-02 temperature and humidity transmitter is designed with an RS-485 communication interface, compatible with standard Modbus-RTU protocol, allowing connection to a Modbus network for temperature and humidity monitoring. The THT-02 uses the SHT3X CMOSens chip, featuring an advanced capacitive humidity sensor and a standard bandgap temperature sensor, delivering improved performance and reliability over previous generation sensors (SHT1x and SHT7x), with enhanced stability in high humidity environments. Address setting is performed via dip switch, enabling simple, convenient configuration without requiring host software, making installation, maintenance, and replacement easier. The device offers excellent long-term stability, low hysteresis, low power consumption, strong resistance to chemical pollutants, and high repeatability. It is suitable for accurate temperature and relative humidity measurements in HVAC systems, communication rooms, warehouses, buildings, and automatic control applications. Measuring range: -40°C to 125°C, compatible with DC 5-24V power supply. Suitable for use in HVAC, farming, and industrial environments.
