I purchased this sensor (Sparkfun Breakout), hooked it up and ran an example sketch and everything works as expected.
My project requires me to measure dust particles in a chamber of air.
I wanted to use this sensor to do so.
I couldn’t find any sketches online to help me implement a particle-detection algorithm. I’m not sure how this could be done (the library itself has only a presence-detection example - is this what I would work off of?). If presence detection is what I would use, which light(s) would be ideal for measuring dust in the air? It’s stated that this sensor can detect smoke in the air. I tried testing the presence detection whilst blasting the sensor with powder and it would either give me false positives, or not be sensitive enough to consistently detect powder/dust.
If anyone is familiar with the science behind particle sensors and can provide me with some insight on how I might be able to utilize the full capabilities of my breakout board, I would really appreciate that.
