THT2 - Temperature and hygrometer for Modbus RTU over RS485
Temperature and hygrometer to measure temperature, humidity and calculate dew point.
The meter is used with a sensor and there are two types of sensors. Either the temperature sensor that only measures temperature. Or the temperature and humidity sensor that measures temperature and humidity and calculates dew point. Each sensor is ordered separately and is available in different lengths. The sensors are connected to the meter with a bayonet coupling.
Communication to the meter takes place with Modbus RTU via RS485. Configuration and testing of the meter is done with the software Modbus Configurator. Testing of the meter can also be done with the PiiGAB M-Bus Wizard software.
The meter can be combined with USB to RS485 cable CAB-115 which combines voltage supply with data communication. In addition, the meter can be connected to an M-Bus network with the Modbus2MBus application in the PiiGAB M-Bus 900S.
