There is a cuboid. One side has a micro oven cloth. The other side has a suction pump. The level of pollution id proportion to the dust deposited on the cloth. This changes the pressure inside the cuboid box. The pressure change is measured using a digital pressure sensor. This pressure is proportion to the dust. Hence this is an efficient system to measure pollution.
So you can measure Dust particles . Have to ever tried mixing it with precipitation? Pratically dust particles do contribute to pollution but a mixture of FOG+SMOKE = SMOG is what hurts a city most.
I do like the idea of getting a delta in pressure to detect amount of dust (pollutant) in your environment . Would love to see some data when you are done.
sure ashiq, I will try uploading my results when it is done... For precipitation it would deal with moisture measurements and i dont think that dust and precipitation can both be measured together.. if there are some possibilities i ll check the results... thank you ashiq...
an interesting way to stay healthy and detect pollution at such a low cost. GOOD WORK!!!
