RS485 sensors are devices that use the RS485 communication protocol to transmit data. RS485 is a standard for serial communication, widely used in industrial, commercial, and agricultural applications due to its robustness and reliability. 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. And it can reliably carry out centralized monitoring jobs with the host computer system.
