PM2.5 Electronic brick is one of the modules in 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 easily to operate.
Characteristic
It is compatible to both 3V/5V devices.
It is compatible to micro:bit or Arduino products.
It is equipped with standard 3 wires GVS interface.
It is of high consistency and accuracy with a real time response, the 0.3 μm diameter particle can be recognized.
With PWM output and serial port supported.
