How it works

Heater (resistor) generating updraft. Infrared light beam from LED has been focused with Lens to sensing point at the center. 
Airborne particles have been taken into the sensor box with the updraft. 
Particle passing through sensing point scatters light, and receptor receive scattered light through the lens and transformed into pulse signal. Pulse per unit time is proportional to the particle concentration.
