This ppd42 based dust sensor gives a good indication of the air quality in an environment by measuring the dust concentration.
Grove dust sensor python.
Plug the dust sensor into digital port d8 on the grove base shield.
The python source could run directly with python file and python3 file.
The new version of the dht11 module replaces resistive humidity components with capacitive humidity components.
Lpo time is proportional to pm concentration.
No other values have printed on screen in nearly 15 minutes.
Grove temperature amp.
Here is a demo to show how to obtain pm concentration data from this grove dust sensor.
Neither appear to work.
It can only be d8 because the operation of this sensor involves sampling.
How to update me.
Add demo code at the near top of source file.
The particulate matter level pm level in the air is measured by counting the low pulse occupancy time lpo time in given time unit.
This function only can be achieved by d8 the input capturing pin of atmega328p on arduino seeeduino.
The temperature and humidity measurement range are wider.
