The CHT-SHT30-485 probe-type temperature and humidity sensor utilizes an integrated temperature and humidity probe for data acquisition. Processed signals are output directly via the 485 interface by the main control chip. This sensor employs an imported digital temperature and humidity data acquisition module, pre-calibrated at the factory. It offers digital output for both relative humidity and temperature, ensuring excellent accuracy, linearity, repeatability, interchangeability, and consistency. It is suitable for environmental equipment, instrument integration, and general environmental testing.
