Wireless CO2 sensors
Measure the indoor air quality in each room or zone
Our wireless multi-sensors measure and monitor the carbon dioxide (CO2) levels, ambient temperature and relative humidity in a room or zone. 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.
Get accurate, reliable indoor air quality updates
The sensor sends CO2, temperature and humidity measurements every 5-15 minutes. Designed for fitting at head height to ensure accurate air quality readings.
Solar-powered for easy install and low maintenance
The sensors use ambient room light – natural or lighting – for power, making them super easy to install and very low maintenance.
Access real-time data locally or in the cloud
CO2, temperature and humidity data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi — using Pressac’s smart gateway.
- Small, discreet sensors simply stick to the wall
- Measures ambient carbon dioxide (CO2), temperature and relative humidity:
- CO2 0-2550PPM (accuracy +/- 125PPM)
- Temperature 0-51ºC (accuracy +/- 0.5ºC)
- Humidity 0-100% RH (accuracy +/- 5%)
- Reports every 5 minutes when solar-powered or 15 minutes
- Solar-powered using ambient room light – optimally angled
to absorb light – with a battery back-up for periodic
low-light conditions. Batteries typically last up to 10 years
