# Test Application for the Amphenol SM_PWM_01C infrared dust sensor
|
|
|
|
## About
|
|
|
|
This is a simple test application for the SM_PWM_01C driver.
|
|
|
|
## Expected result
|
|
|
|
If everything works then you should see the progress bar vary if dust
|
|
concentration changes in the room, or manually block the infrared inputs
|
|
to force a change.
|
|
|
|
Overly exaggerated values (blocked infrared sensor) can be seen here:
