Why don’t my AirBeam2 readings match with readings from another air sensor that measures PM?

It is not uncommon for two different types of sensors to give you different readings. Possible reasons for different readings include:

1. It could be due to something you are doing (for example covering the air inlet or exhaust)
2. One sensor might be dirty or damaged
3. The type of technology used in each sensor is different
4. The sensors are placed inside their protective housings differently
5. Different sensor manufacturers may analyze data differently before sharing it with a user

It’s still a good idea to operate sensors together for a while to learn how the readings compare.
