This tutorial is about connecting an M5Stack ATOM running MicroPython to the Google Cloud Platform (GCP) to collect air-quality variables obtained from reading two sensors:

  • BME680: a gas sensor that integrates high-linearity and high-accuracy gas, pressure, humidity, and temperature sensors. 
  • PMSA003A: a digital and universal particle concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles and output them to a digital interface.
