Indoor air quality (IAQ) sensors

Monitor air quality in each room and send your data straight to your chosen cloud

Get real-time indoor air quality updates

Our indoor air quality sensor accurately measures the carbon dioxide (CO2), volatile organic compounds (VOCs) and particulate matter (PM), temperature and humidity levels in a room.

These small, discreet sensors wirelessly connect to our smart gateway, which then sends data straight to your preferred IoT platform. Allowing you to integrate near real-time data into your systems and ensure conditions are at optimum levels.

Pressac Environmental Sensor

Monitor the air quality in a room or zone with a single sensor

Monitor all aspects of air quality

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 accurate updates every 5-60 minutes

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

Access data locally or in the cloud

Data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi. No subscriptions or recurring fees.
