Nettigo Air Monitor (KIT 0.3.2) - Build your own smog sensor!

This KIT requires soldering and basic manual skills. Before assembly you should know how to solder and use screwdriver.

What's the deal with NAM sensor

NAM sensor is based on Luftadten project. Thus Your sensor automatically will send data to Luftdaten sensor network (aka Your sensor is on Luftdaten map). It has better case and it is soldered on dedicated PCB. No more data loss due to faulty jumper wire. And, in our opinion most important difference: heating chamber with automatic air conditioning to keep relative humidity below 70%. Why it is so important?

This figure shows PM10 readings from two SDS011 based sensors with RH close to 100%. One is equipped with heating chamber (green line) and one is not (yellow line). Without heating and control element in RH higher than 70% You can observe condensation. With this process water and dust particles combine making more and bigger objects. Optical sensors can return readings few times higher when condensation phenomenon is present.
