grove-Laser_PM2.5_Sensor-HM3301 sporadic readings

[tim-oe]

i adapted the file
https://github.com/Seeed-Studio/grove.py/blob/master/grove/grove_PM2_5_HM3301.py
and did a slight adaptation to breakout the data from the reading
https://github.com/tim-oe/WeatherWatch/tree/main/weatherwatch/sensor/aqi

the sensor is being read every 15 minutes and they seem to jump up and down.

i have it mounted in a vertical position, wondering if that would impact it?

I got a Grove, and indeed noticed abnormal fluctuations in readings, which seemed to have nothing to do with installation. I will further investigate it. Thank you for your question.
