This module uses the principle of optical LASER light scattering to measure the concentration of particulate matter (PM2.5 and PM10) in the air. It consists of a LASER diode, a photodiode, a microcontroller, a low-noise amplifier and a suction fan.
The suctioned air passes through the detection chamber, where the LASER light striking the suspended dust particles is scattered in all directions and trans
Any beginner friendly projects on the horizon for this little gem? I have been wanting to make a small weather station/air quality indicator system of some sort to warn us allergy sufferers of inclement conditions before we leave for work.
