I’m having difficulties getting my Grove Dust Sensor to take any readings. I run the dust sensor code from https://github.com/DexterInd/GrovePi/blob/master/Software/Python/grove_dust_sensor.py on my pi 3 with grove pi plus but it just outputs “reading from the dust sensor” on the command line, with no readings (left it running for about 15 mins to give it time to warm up). The Python code for the sensor is quite short so I’m not sure where it is going wrong. Has anyone got any debugging tips or tests that would be worth trying to narrow down where the problem might be?
Any help or pointers would be greatly appreciated!
