CO2 Humidity Temperature Sensor | Wireless - Pressac Skip to content

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.
