Air quality sensor suits indoor and outdoor monitoring

This air quality sensor accurately measures temperature, humidity, particulate matter, Total Volatile Organic Compounds (TVOCs), and equivalent carbon monoxide (eCO₂).

Suitable for indoor and outdoor monitoring, the SN-GCQB1 air quality sensor is ideal for the retail, medical, and smart building industries. The sensor supports a range of applications, including HVAC systems, air purifiers, greenhouses, and industrial and manufacturing facilities.  

It uses a high-precision optical sensor and laser diode to detect particulate matter, including dust, fly ash, soot, smoke, aerosols, fumes, and condensing vapours. The air quality sensor can also monitor emissions from construction materials, fireplaces, forest fires, and waste incineration. The SN-GCQB1 sensor features an optimized air pathway structure to reduce particulate accumulation and safeguard electrical components.

An onboard microprocessor and micro-fan improve the sensor's functionality and efficiency, while auto-calibration ensures accurate measurements for a usable life of over ten years.

The sensor has a resin outer shell that protects it against electromagnetic radiation for long-time drift performance, measurement stability, and response time.

Measuring 37 mm x 37 mm x 12mm, the all-in-one air quality sensor is ideal for wearables, smart home applications, and other compact devices.

It measures relative humidity from 0% to 100% with ±3.0% accuracy and temperatures from -10°C to +60°C with ±0.4°C accuracy.

The sensor is designed to identify particulate matter in three critical categories: PM1.0, PM2.5, and PM10.
