Article Snippet: .. These technical requirements were set to obtain a versatile device that could cover the typical indoor and outdoor concentration range for these pollutants, and be used both for stationary or itinerary applications, considering that one is rarely commuting more than 2 h. Based on the requirements listed above, our partner HEPL (Haute École de la Province de Liège) chose to use: • the Adafruit BME680 breakout for relative humidity, temperature and barometric pressure, which was chosen over the BME280 in the course of the project; • the SparkFun GPS-12751 module breakout for location; • the SparkFun MMA8452Q breakout for triple-axis acceleration; • the Sensirion SPS30 sensor for PM1, PM2.5, PM4 and PM10 and the Honeywell HPMA115S0 sensor for PM2.5 and PM10; • the Alphasense NO-A4, NO2-A43F and OX-A431 electrochemical sensors respectively for nitric oxide, nitrogen dioxide and ozone concentration (after subtracting NO2); • the Texas Instrument LMP91000 Analog Front End (AFE), which is at the core of the “current to concentration” conversion for the considered gas sensors; • the Microchip ATmega2560, which is an 8-bit microcontroller with, among others, a 16-channel 10-bit A/D converter (ADC) that achieves 16 MIPS at 16 MHz. ..

Results of the application of the linear correction algorithm described above. The initial correlation is the value of R 2 for the LCSs compared with the reference instrument; the final correlation is the value of R 2 * after the correction has been applied; and the entity of the applied correction can be seen from the values of the slope and intercept of the linear regression curve. The score is based on the value of the R 2 , ranging from 1 for R 2 < 0.2 to 5 from R 2 > 0.8.
