The Humidity Data Logger has both temperature and humidity measuring capabilities in a single sensor. This extends the capability of the sensorProbe to measure up to 8 temperature and 8 humidity sensing parameters, just by connecting 8 dual sensors. Up to 2 dual sensors can be plugged into RJ-45 jacks on the SensorProbe2 and up to 8 on SensorProbe8, SensorProbe8-X20/X60 and SecurityProbe. The CAT5 Enabled version allows you to place the sensor up to 1000 feet from the SensorProbe using standard CAT5 cable (5 ft cable included). There is also a waterproof version of the sensor available if there is a chance that the sensor end could be submersed in water.
When the Humidity Data Logger is plugged into the sensor RJ-45 port, the sensorProbe will auto detect the sensor, and it will display Temperature & Humidity for each RJ-45 port. A built in graph option is included on all sensorProbes for graphing temperature and humidity variations over a period of time.
Each sensor has its own SNMP OID so that data can be collected over the network and graphed using an external application like MRTG.
The temperature sensor can be read using included SNMP utilities to allow graphing and datalogging at 0.2°C resolution.
