CO2 , temperature and humidity sensors

Accurately measure CO2, temperature and humidity levels in each room or zone. No cables.

Get accurate, reliable indoor air quality updates

The small and 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 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 cloud-based or on-prem IoT platform, 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 with a battery back-up

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.
