It is not uncommon for two different types of sensors to give you different readings. Possible reasons for different readings include:
- It could be due to something you are doing (for example covering the air inlet or exhaust)
- One sensor might be dirty or damaged
- The type of technology used in each sensor is different
- The sensors are placed inside their protective housings differently
- 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.
