Wireless, self-powered CO2 sensors

Accurately measure the CO2 levels in each room. Wirelessly transmits the data to your chosen IoT cloud via our Smart Gateways.

Get accurate, reliable indoor air quality updates

The small wireless CO2 sensors simply stick onto the wall and are solar-powered using ambient room light, making them easy to install and very low maintenance.

Our wireless multi-sensors measure the carbon dioxide (CO2) levels, ambient temperature and relative humidity in a room or zone. The sensors wirelessly transmit data to your chosen IoT cloud, via our Smart Gateways.

Monitor the carbon dioxide (CO2) levels, ambient temperature and relative humidity in a room or zone

Get accurate updates every 5-15 minutes

Designed for fitting at head height to ensure accurate air quality readings. The sensor sends data every 5 minutes when solar-powered or 15 minutes when battery-powered.

Solar powered

The sensors use ambient room light – natural or lighting – for power, with a backup battery power source giving you continual operation in the evening.

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 — using Pressac’s smart gateway. No subscriptions or recurring fees.
