ETHSA is a wireless temperature & humidity sensor for EnOcean systems. Powered by a solar cell, it works absolutely maintenance-free. An integrated energy store allows operation for several days in total darkness. In dark surroundings, a coin cell battery can be retrofitted.
The small housing can easily be mounted to vertical walls or furniture using the included adhesive pad. Using the included metal stand the sensor can be positioned on horizontal surfaces. One end cap can be replaced by the enclosed lodge cap.
ETHSA periodically measures temperature and humidity of its environment. Significant changes in readings are reported immediately. In addition, frequent updates (signs-of-life) are provided at regular intervals.
