RHS-1
Temperature & relative humidity RS-485 sensor
RHS-1 is a temperature and relative humidity sensor with RS485 interface, designed to work together with RM-408. Depending on the power source, the connection with the sensor is established via 3 or 4-wire RS-485 interface. Power can be supplied from RM-408, or from external power supply if the line is too long (> 50 meters).
