Measuring air pollution wthi lowcost sensors

signal from the air pollutant can be strong, but at ambient air levels the signal is weaker in comparison to the interfering effects. The quality of sensor results therefore depends on technology and implementation (application, site, conditions, setup). Reproducing sensor responses at different measurement sites or the portable use

The 3 Types of Particle Detectors: How We See the Invisible

The detector is a chamber with an air current going through it. On one side of the chamber, there is an infrared emitter (like a light bulb), and on the other side, there is an infrared sensor. Each particle in the air blocks a little bit of light, meaning that a little bit less of it will reach the sensor. In other words, the light gets dimmer.
