Description
PM2.5 Electronic brick is one of the modules in the Octopus series to test the PM2.5 concentration. Based on ZH03 laser dust sensors, it can test the dust particle in the air with high consistency and stability. The PWM output and serial port design also make it easy to operate. CHARACTERISTIC It is compatible with both 3V/5V devices. It is compatible with micro:bit or Arduino products. It is equipped with a standard 3-wires GVS interface. It is of high consistency and accuracy with real-time response, the 0.3 μm diameter particle can be recognized. With PWM output and serial port supported. DIMENSION Diagram for Pins Connector Introduction to Main Function Modules ZH03B Sensor 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 the 3.3V PWM signal. 4PIN Serial Output Interfaces The output interfaces are used for the 3.3V serial signals. QUICK START Hardware Connection Connect PM2.5 electronic brick module to P1 the port on micro:bit with a micro:bit expansion board.
