The RHT-01-GN sensor is a device used to measure relative humidity. It is equipped with a modern, pre-calibrated digital sensor of humidity and a microcontroller to control sensor’s operation, perform calculations and communicate with external devices. The sensor has a RS-485 interface and it is used to interoperate with the JOTAFAN regulators (with RS-485), however, it is also possible to create the system of measurement with any other master device (e.g. a PC computer), with a protocol that enables connection of up to 32 sensors.
The sensor is equipped with a hermetic plug that makes its disassembly easier and faster e.g. during building cleaning.
A hermetic plug for mounting on the connecting cable is included in the set. The sensor can be used to measure low or medium humidity (0..90%RH) in different buildings, especially in pig houses, poultry houses and barns.Technical Data:
