Gravity: SGP40 Air Quality Sensor Brand_M5Stack This chip has a whopping

This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)

This means it's also not water-proof or weather-resistant

But you either need an Arduino or they might be a little too big and powerful for your needs

Gravity: SGP40 Air Quality Sensor Brand_M5Stack This chip has a whoppingThe SGP40 Air Quality sensor adopts the new SGP40 digital VOC sensor chip launched by the well known Sensirion. Based on the Sensirions CMOSens technology, the SGP40 offers a complete sensor system on a single chip, a temperature controlled micro hotplate and a humidity compensated indoor air quality signal. In combination with Sensirions powerful VOC algorithm, the sensor signal can be directly used to evaluate indoor air quality. It features low
