Disassembling Ambient Weather AQIN Particulate Sensor

Looking at the sensor from the bottom, you can see the two tabs/prongs that hold the outer case together.

The internal housing will now be exposed. You can use the two tabs/prongs on this porting to remove that portion of the case.

Next, you can remove the 4 small screws holding the internal components to the outer shell.

Once the unit is disassembled, you can locate the internal motor of the unit.

Using compressed air, you may remove any debris that has become lodged on the intake shield of the motor.
