Measuring air pollution wthi low-cost sensors

In a metal oxide sensor (resistive sensor, semiconductor) gases in the air react on the sensor surface and modify its resistance. A photo ionization detector ionises volatile organic compounds and measures the resulting electrical current. Optical particle counters detect particulate pollution by measuring the light scattered by particles.
