Dust Sensor Detector Module(EF05027)


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.

ELECFREAKS PlanetX Dust Sensor


Designed in RJ11 connections, easy to plug.


Type of ConnectionDigital output
Working Voltage3.3V
Sensitivity0.5V /(100μg/ m3)
Effective Scope500μg/ m3


Quick to Start

Materials Required and Diagram

Connect the Dust sensor to J1 port and the OLED to the IIC port in the Nezha expansion board as the picture shows.

MakeCode Programming

Step 1

Click "Advanced" in the MakeCode drawer to see more choices.

We need to add a package for programming, . Click "Extensions" in the bottom of the drawer and search with "PlanetX" in the dialogue box to download it.

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:


You can also download it directly below:


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

Python Programming

Step 1

Download the package and unzip it: PlanetX_MicroPython

Go to Python editor

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

Step 2


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

dis = DUST(J1)
while True:


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