Octopus Electronic Bricks! You can use them build electronics projects just as easy as piling bricks! By using Octopus electronic bricks, you may connect Arduino or compatible boards easily with various digital, analog and I2C/Uart interfaces. These breadboard-less firm connections includes an extensive collection of modules like potentiometers, sensors, relays, servos, and even buttons. Just plug and play!
The Octopus PM2.5 module is based on ZH03 laser dust sensors. It can test the dust particles in the air with high consistency and stability. The PWM output and serial port design also make it easily to operate.

Introduction to Main Function Modules
ZH03B sensor is used to test the PM2.5 concentration in the air.
3PIN Standard GVS Electronic Brick Interfaces
With standard 3PIN electronic brick interfaces, "S" is the output pin for 3.3V PWM signal.
4PIN Serial Output Interfaces
The output interfaces are used for 3.3V serial signal.
Connect PM2.5 electronic brick module to P1 port on micro:bit with a micro:bit expansion board.
