ZENNER Indoor T+H Sensor wM-Bus
Temperature and humidity sensor with wireless M-Bus or LoRaWAN® radio interface
The Indoor T+H Sensor records the temperature and relative humidity of indoor spaces. The sensor supports the user in optimizing the heating and ventilation behavior. The current temperature and humidity values can be read on the device display at any time.
The data collected and stored by the device is transmitted to downstream recording systems using wireless M-Bus or LoRaWAN® radio technology. This creates transparency regarding the heating and ventilation behavior in order to be able to derive possible efficiency and optimization measures. This data can be used, for example, to prevent mold formation.
The temperature and humidity measurement takes place internally in the device every three minutes. The average value for the last quarter of an hour is determined from the measured values, saved and added up in the register of the respective temperature or humidity range. The
Radio transmission occurs every 20 seconds for wireless M-Bus and hourly for LoRaWAN®.
