ST814 Temperature/Humidity Detector
The Temperature/Humidity Detector is a Z-WaveTM enabled device which is fully
compatible with any Z-WaveTM enabled network. Z-WaveTM enabled devices
displaying the Z-WaveTM logo can also be used with it regardless of the
manufacturer, and ours can also be used in other manufacturer’s Z-WaveTM
enabled networks. Inclusion of this detector on other manufacturer’s Wireless
Controller menu allows remote operation of connected modules when the
detector is triggered.
The Temperature/Humidity Detector is designed to monitor the current
temperature and humidity of ambient environment. The reading of
temperature/humidity can be reported to you on a regular base at your disposal.
If temperature/humidity reaches set points, the detector will send alerts to
associated devices for further execution. Since sudden temperature/humidity
change may cause health problems to people such as elderly or very young
children, Temp./Humid. Detector provides you most up-to-date temperature and
humidity reading for you to watch your family’s health.
