Wireless temperature and humidity sensors

Measure and monitor the ambient thermal conditions in each room or zon

Get accurate, reliable temperature and humidity data

Our wireless multi-sensors measure the ambient temperature and relative humidity in each room, cabinet or zone.

The small, solar-powered sensors use ultra-low-power wireless technology, making them easy to install and very low maintenance. Now with battery back-up for low-light environments.

Monitor comfort levels in spaces

Get accurate, reliable climate updates

The sensor sends instant updates if the temperature changes by more than 0.5°C or humidity changes by more than 2%.

Solar-powered with battery back-up for easy install

The sensors use ambient room light – natural or lighting – with a battery back-up, making them super easy to install and very low maintenance.

Access real-time data locally or in the cloud

Data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi through an MQTT broker or ready connections to AWS and Microsoft Azure. No subscriptions or recurring fees.
