Air Quality Sensor FAQs

What parameters do our IAQ sensors monitor?

Our IAQ sensors measure multiple environmental conditions in real time, including carbon dioxide (CO₂) levels, total volatile organic compounds (TVOCs), particulate matter (PM1, PM2.5, PM4, PM10), ambient temperature, and relative humidity. This comprehensive monitoring makes them ideal for smart building environments and indoor air quality compliance.

How often do our indoor air quality sensors send data?

Our indoor air quality sensors transmit environmental data at configurable intervals ranging from every 5 minutes to every 60 minutes. The default setting sends data at a randomised 15-minute interval to avoid wireless transmission conflicts.

Can you configure our air quality sensors remotely?

Yes, Pressac's IAQ sensors are fully configurable either via onboard DIP switches or remotely using the EnOcean ProComm software. You can adjust reporting intervals, enable secure communication, and calibrate sensors remotely, supporting scalable building automation projects.

Do our IAQ sensors require manual calibration?

Pressac’s indoor air quality sensors come pre-calibrated from the factory and also support both automatic and manual recalibration. CO₂ auto-calibration occurs over a 7-day rolling period, while TVOC levels recalibrate automatically every 24 hours. Manual calibration can be done on-site using DIP switches or via the EnOcean ProComm software.

What wireless communication protocol do our sensors use?

Our IAQ sensors communicate via the EnOcean wireless protocol, operating at 868 MHz in Europe and 902 MHz in North America. With an indoor range of up to 30m and AES-128 encryption. Our sensors ensure secure, low-energy wireless data transmission ideal for commercial building applications.

Can our air quality sensors be used as EnOcean repeaters?

Yes, Pressac’s indoor air quality sensors can be configured to act as EnOcean repeaters. This allows them to extend the wireless communication range of other EnOcean-based smart building devices, improving system reliability in larger installations.

What platforms and systems can our air quality data integrate with?

Our indoor air quality sensors seamlessly integrate with leading IoT platforms and data systems including MQTT brokers, Azure IoT Hub, AWS IoT Core, Google Sheets, and Node-RED. This ensures compatibility with digital twin platforms, BMS (Building Management Systems), and smart HVAC automation.

Are there any ongoing subscription fees with our IAQ sensors?

No, Pressac air quality sensors are designed with zero recurring fees. All data is transmitted securely and locally via the EnOcean wireless protocol and can be routed to your preferred platform using our gateway, eliminating reliance on third-party cloud subscriptions.

Where should our IAQ sensors be installed?

For accurate measurement of air quality, we recommend installing sensors on an internal wall at a height of approximately 1.8m, away from doors, windows, and ventilation sources. The particulate matter intake should face downward to ensure accurate PM detection.

What certifications do our IAQ sensors carry?

Our indoor air quality sensors are RESET AIR-accredited and meet a wide range of industry standards including CE, FCC, RoHS, and WEEE. They are designed and manufactured in the UK under ISO 9001, ISO 14001, and ISO 27001 quality systems.

What power supply options are available?

Each sensor is powered via a standard 5V USB mains adapter (included). For enterprise installations, our air quality sensors can also be powered using Power over Ethernet (PoE) adapters for simplified infrastructure deployment.

What are the physical specifications of our IAQ sensors?

Pressac’s air quality sensors are compact, measuring 110 × 110 × 39mm and feature a durable ABS enclosure with an IP2X protection rating. The operating temperature range is -10°C to 55°C, making them suitable for a wide variety of commercial and industrial environments.

Do our air quality sensors support encrypted communication?

Yes, Pressac IAQ sensors support AES-128 encrypted communication for secure wireless data transfer over EnOcean. Secure mode can be activated using the “Learn” button and DIP switch configuration during commissioning.

How are our IAQ sensors commissioned and added to a system?

Commissioning is quick and straightforward. After mounting and powering the sensor, users press the “Learn” button to transmit an EnOcean signal telegram. The device can then be registered manually or automatically via a Pressac gateway.

How do our IAQ sensors work?

Our technology is system agnostic, the data from our sensors can be used in any way you need. There are different options to choose from, making it easy to get your data in the way that’s right for you.
