Sensirion SEN68 Particulate Matter Sensors
Sensirion SEN68 Particulate Matter Sensors are compact, all-in-one environmental sensor modules for indoor air quality applications. The SEN68 measures up to nine environmental parameters, including PM1, PM2.5, PM4, PM10, temperature, relative humidity, VOC Index, NOx Index, and HCHO.
The SEN68 combines multiple sensors into a single form factor to simplify integration, reduce costs, and enable customization across different product tiers. At the core of the module is the SPS6x, a miniaturized MEMS-based particulate matter sensing component that integrates the light source, detector, signal processing, and algorithm into a cost- and space-efficient solution.
The Sensirion SEN68 Particulate Matter Sensors are designed for air purifiers, HVAC/ventilation systems, air conditioners, and air quality monitors. The device is ideal for applications that require support for IAQ standards such as RESET® and the WELL Building Standard™.
