RFTF RS485
Room humidity and temperature sensor with RS485
Application
The RFTF RS485 is a humidity/temperature sensor whose signal communicates via RS485 and by means of Modbus®-RTU / S-Bus and measures the relative, absolute humidity and temperature of the air, e.g. in refrigeration, air-conditioning and clean room technology, in living rooms, offices, hotels, technical rooms, assembly and conference rooms.
