This Z-wave temperature and humidity sensor is designed for table and wall use. The unit has an LCD display that displays the temperature or humidity and sends the data frequently to a z-wave controller. The 4 buttons can be used to switch between different views (minimum, maximum or actual values of humidity and temperature). both celcius and fahrenheid can be set.
The Z-wave device passes the values trough to the z-wave controller. It is possible to set triggerpoint where the device wakes up and sents data to the controller.
Example : Automatic Bathroom Ventilation.
