DUST SENSOR MODULE
1. Scope of application
The Dust Sensor Module STBM 271 detects the level of indoor airborne dust, particles, and
pollen, and is ideal for use in stand-alone air cleaner or IAQ monitor applications. The PWM output of the sensor
can be connected directly to a µ-processor to control fan speed or ventilation and also to display the
concentration of particles. Detectable size of particles is limited to about 1 µm.

Usage in security relevant applications (for example smoke or fire alarm) is not allowed.
