Experiments with air quality sensors Scripts in this directory read from sesor serial port output (which is 3.3V serial connected to usb serial dongle) and store data to influxdb using curl. When receiving data from sensors, they check header and checksum to avoid sending garbage data. This also helps when you select wrong serial port, beacuse script from wrong sensor won't send invalid or corrupt data. Timestamp are also generated locally to mitigate any network latency to influxdb (which is somewhere in the cloud, and latency can vary just enough to create empty vertical stripes in graphs which is ugly and incorrect).
