   • Install the package

3. Install Required Libraries

Data Format

The output is CSV formatted with the following columns:

Timestamp(ms), PM1.0(ug/m3), PM2.5(ug/m3), PM10(ug/m3), 
V_CH1(V), I_CH1(mA), V_CH2(V), I_CH2(mA), V_CH3(V), I_CH3(mA), 
Temp(C), Humidity(%), Pressure(hPa), GasRes(KOhm), Altitude(m)

Example output:

2000,12.50,15.30,18.20,5.000,125.50,3.300,45.20,12.000,200.00,22.50,45.30,1013.25,150.45,10.25
