In industrial and building automation, high-quality and inexpensive probes are needed which are particularly suited for continuous use. The innovative humidity- and temperature probe with digital I²C-interface meets these requirements exactly.
This humidity- and temperature probe can be connected directly to a microcontroller or regulator. With the Hytelog-Multisensor with software (available as accessory) the probe can operate directly on a PC. This enables recording and presenting measuring values and many controlling and regulating options. This is easily made possible by the optional software ProfiLab Expert 4.0 and the relay module (available as accessory).
With the Hytelog humidity and temperature measuring system you have the option of connecting 3 sensors at the same time. The temperature or humidity sensors can be easily connected via the three RJ12 sockets. It only has to be considered that the sensors have different I²C addresses. When used with the Hytelog multisensor, only the addresses 0x28,0x29 and 0x2A are permitted.
Areas of application:
- Building automation
- Industrial measurement and control technology
