Temperature & Humidity Sensor
Our wall-mounted temperature and humidity transmitter uses a high-performance sensing chip for accurate barn climate measurement. It supports RS485 (Modbus-RTU) output, connecting directly to PLCs, controllers, and cloud data centers. The IP65 housing withstands dust and moisture in livestock facilities, while interchangeable probes (copper, PE, dust-proof, waterproof, high-temperature) cover environments from -40°C to +120°C. Wide DC 9-36V power input and PC configuration tools simplify installation and maintenance.
