Measure the indoor air quality in each room or zone with a single sensor
Our indoor air quality (IAQ) sensor measures carbon dioxide (CO2), volatile organic compounds (VOCs), and particulate matter (PM) levels, as well as temperature and humidity in a room. These small, discreet sensors can be mounted on a wall or table. Producing near real-time, highly accurate data which you can use to ensure your indoor air quality is at optimum levels at all times.


Monitor all aspects of air quality
Our sensors measure ambient carbon dioxide (CO2), total volatile organic compounds (TVOCs), particulate matter (PM1/2.5/4/10), temperature and relative humidity, all in a single sensor

Get regular air quality updates
Designed for fitting at head height to ensure accurate indoor air quality readings, our sensor sends reliable readings every 5-60 minutes.

Access real-time data locally or in the cloud
Air quality data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi — using Pressac’s smart gateway.
