Relative humidity and temperature sensor DB801

wall-mountRS-485Modbus

RS485 Output Humidity and Temperature Sensor for Indoor Using DB801 sensors are RS485 bus type temperature and humidity sensors with RJ45 interface, which can realize multi-point simultaneous monitoring, networking and remote transmission, on-site digital display and other functions. It is used for data communication in computer rooms, archives, libraries,warehousing, offices and other environments, and it can be directly connected with various control equipment, display instruments and computers. One network can monitor up to 32 points. This series of temperature and humidity sensors also have a display screen, which can directly observe the temperature and humidity changes in the field.
