Product Description

Integrated RS485 Modbus SHT20 Digital Humidity Temperature Sensor

Votesen VTH200-T RS485 integrated digital humidity temperature module adopts high precision Sensirion SHT2x sensor equipped with a high-quality filter shell for large air permeability, fast gas humidity flow and exchange rate. The probe adopts the industrial universal standard RS485 bus MODBUS-RTU protocol interface, which is convenient for accessing various instruments or systems such as PLC and DCS for monitoring the state quantity such as temperature and humidity. This is a high-precision industrial-grade RS485 temperature and humidity sensor. It uses high-quality digital integrated transducer and reliable digital processing circuit to convert the temperature and humidity in the environment into corresponding RS485 signals. The product has remarkable long-term stability, low latency, high resistance to chemical pollution, and superior repeatability. It is an ideal solution for accurately measuring relative humidity and temperature in HVAC (Heating, ventilation, and air conditioning) applications. This sensor can be widely used in building automation, climate and HVAC automatic control, climatology stations in museums and hotels, closed-loop control of HVAC systems, etc.
