27. Dust Sensor Detector Module

27.1. Introduction

The Dust Sensor Detector Module with Sharp GP2Y1010AU0F adopts Sharp optical dust sensor(GP2Y1010AU0F). It is used to detect the density of dust particle with diameter beyond 0.8μm such as cigarette smoke.

Note: If you met a tip indicating that the codebase will be deleted due to incompatibility, you may continue as the tips say or build a new project in the menu.

Step 2

Code as below:

Result

  • The value detected by the Dust Sensor displays on the OLED screen.

27.7. Python Programming


Step 1

Download the package and unzip it: PlanetX_MicroPython

Go to Python editor

../_images/05001_072.png

We need to add enum.py and dust.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add enum.py and dust.py from the unzipped package of PlanetX_MicroPython.

Step 2

Reference

from microbit import *
from enum import *
from dust import *

dis = DUST(J1)
while True:
    display.scroll(dis.get_dust())
    sleep(500)

结果

  • The value detected by the Dust Sensor displays on the micro:bit.
