最佳解
1. This solution dust sensor is using Sharp GP2Y1010AU0F, and this sensor AFE is using Ti OPA2330 and INA132. (pic. 1).
2. From Ti application note that shows this design accorancy around 75% for PM10 (pic 2).
3. Because detail test report very large, so I just attached Ti test equipment and enviroment here (Pic 3).
If you hope to study whole test report that you can download it from Ti website.
