Which one has used the GP2Y1010AU0F dust detection sensor module, I have a circuit diagram converted with ADC0832, but found that the test seems to have a problem, the data has been very small, the initial estimate is that the sensor's pin 3 (LED) connection method is born Question, I hope to give pointers, thank you very much.

Hello there! This is the device parameter given in the official website manual.

My understanding is that the pin is also the positive electrode of infrared. My routine here is that the pin is directly grounded and there is no control. I found that its test result seems to be wrong. Do I have to use an MCU to control it? How to control it.

Pin 3 and pin 5 of the chip are the signal input and output. The c4 capacitor can be removed. The high level of pin 5 can be accessed by resistor division. It should be almost the same. Try it.
