Tzone temperature and humidity transmitter THT03R is designed based on the RS-485 communication interface, compatible with the standard Modbus-RTU protocol. It can be connected to the Modbus network to achieve temperature and humidity measurement and monitoring.
Using SHT30 sensor, and it improves its stability in high humidity environment. Adopts DIP switch to set the address to facilitate sensor identification. With a large LCD screen, you can check the current temperature humidity data and machine status in time.
Low power consumption, strong resistance to chemical contamination, and low latency. It is widely used in measuring temperature and humidity data in HVAC, communication rooms, warehouses, automatic control applications, etc.
