- Air quality sensor (Winsen ZH03B) for PM1, PM2.5 and PM10 output by Python
- Check out the datasheet
- Use a USB UART adapter and plug to USB port is the easiest way to get started.
- Pin 4 on ZH03B <----> TX pin on adapter
- Pin 5 on ZH03B <----> RX pin on adapter
- 5V and GND
The sensor constantly output the PM1, PM2.5 and PM10 readings
A request sent to the sensor by the PC, the sensor returns the PMs reading
with addition to turn on and turn the sensor. The fan was tested as it can be turned on and off. Not sure about the diode.
- run
examples.py, make sure you get the correct USB port. Check it by run on terminal (Linux:ls /dev/ttyUSB*) - the format reading look like this:
Sat Feb 8 16:03:57 2020
PM1: 17, PM2.5: 21, PM10: 23 in ug/m3
- run
examples_log_data.py. This allows to run the sensors until terminated the script. The data is saved into a CSV file CSV file
