Hi sir

How is the sensor converts the received pulse output into equivalent voltage depending on the dust available?

Thanks

Hi sir!

I am using amphenol dust senor SM-PWM-01A to know the dust levels in our soldering area. Its output is PWM and I am unable to convert the output into mg/m3. So please kindly provide the necessary information required if anyone know it.

Thanks

Hi Frederick!

Wow -that's very interesting. It is definitely a dramatic difference in measurement, I didn't realize this sensor would be so effective! I've added one to my list to purchase.

It's great that it has all analog processing built-in.

Thanks for all the posts!

Have you considered that the dust will accumulate inside the air sock and skew your readings?

You might want to have a small blow through chamber to concentrate your air sample, but make sure it is blown away before the next sample is taken.

Good work, Frederick.

Have you tried running it without a fan?
