Using the BMV080 Particulate Matter PM2.5 Sensor
3+
4+
This Example shows how to read and set the parameters of the BMV080 sensor.
5+
6+
These include:
7+
volumetric_mass_density
8+
integration_time
9+
distribution_id
10+
do_obstruction_detection
11+
do_vibration_filtering
12+
13+
After these parameters are read and set, This example shows how to use the
14+
sensor in "continuous mode" to get particulate matter readings once every
15+
second.
16+
17+
It uses polling of the device to check if new data is available.
