My progress this week was mostly comprised of me testing the sensors that have arrived.
The PM 2.5 sensor, DHT22 temperature and humidity sensor, Grove Air Quality Sensor, and MQ-135 mixed-gas sensor were tested, and all were found to be fully functional, capable of collecting and displaying data via Arduino IDE's serial monitor and serial plotter.
It should be noted that for the MQ-135 sensor, it was recommended for it to be powered on with a 5V power supply continuously for more than 24 hours, as it needs some "burn-in" time for its sensor to adapt to clean atmospheric air before it can becomes sensitive towards harmful gases.
Also, the second batch of components for my project, those being the ones ordered from my.Element14, arrived this week.
