Square Air for LoRaWAN

VOC, Air QUALITY, CO2_eq, TEMPERATURE, HUMIDITY, AMBIENT LIGHT, AIR PRESSURE

Meet Square Air — invisible air quality sensing for intelligent airflow.

Blend-in design

Long-range (2 km)

Simple installation & mounting

Detects a wide spectrum of air pollutants

Detects perfume, sweat, organic decay & more

All-in-one air quality sensor

Indoor

Square Air is designed to reflect how air actually behaves in real environments. Instead of focusing on a single metric, it detects a broad mix of volatile organic compounds (VOCs)—a diverse group of airborne chemicals responsible for both pollutants and odors like perfumes.

These compounds are emitted not only from building materials and cleaning products, but also from everyday human activity such as breath, sweat, and biological processes. This means the sensor responds to real-world signals like poor ventilation, body odor, heavy fragrance, or even early signs of organic decay.

With long-range LoRaWAN connectivity and ultra-low power consumption, Square Air enables scalable monitoring across buildings—helping you understand, optimize, and act on indoor air quality as people actually experience it.

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 12 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.
