Square Air LoRaWAN
Square Air is an advanced multi-sensor designed for comprehensive indoor air quality monitoring. It measures air quality index (IAQ), CO2 equivalent (CO2e), bVOC, temperature, humidity, barometric pressure, and ambient light, providing a complete picture of indoor environments.
Powered by the Bosch BME688 AI-enabled gas sensor, Square Air acts as a digital nose, capable of detecting a wide range of airborne substances and enabling smarter, data-driven ventilation and energy optimization.
With a compact design (58 × 58 × 15 mm) and a high-capacity battery, it delivers up to 15 years of operation (depending on usage profile), making it ideal for long-term deployments in buildings and facilities.
Typical use cases
- Indoor air quality monitoring in offices and buildings
- Smart ventilation and HVAC optimization
- Schools, hospitals, and public environments
- Workplace health and productivity monitoring
- Detection of air quality deviations and anomalies
Key advantages
- Advanced air quality sensing – IAQ, CO2e, bVOC and multiple environmental parameters
- AI-powered gas detection – Bosch BME688 enables detection of complex air compositions
- Long battery life – up to 15 years depending on usage profile
- Multi-function sensor – combines air quality, climate, and ambient light sensing
- Easy configuration – via NFC using Sensative’s NFC app for Android smartphones
- Discreet and compact design – suitable for professional environments
Important note on CO₂ measurement
Square Air estimates CO2 equivalent (CO2e) based on detected VOC levels related to human presence.
It is not designed for detecting CO₂ leaks from pressurized systems or gas installations.
Advanced capabilities
Square Air can be trained to detect specific gases or substances using AI-based configuration of the BME688 sensor, enabling tailored applications for specialized environments.
This functionality requires training. Please contact Sensative for more information.
Installation
Square Air can be mounted using the integrated adhesive for quick installation, or with the Sensative Square Screw Mounting Kit (optional) for secure and permanent mounting.
Smart geolocation (without GPS)
Square Air supports cloud-based Wi-Fi geolocation, enabling positioning in indoor or GPS-denied environments by scanning nearby Wi-Fi networks.
This functionality requires a compatible cloud service such as Sensative Yggio.
