teetrinkerI'm playing around with #esp32 and a #adafruit #sgp40 sensor for getting air quality readings. This one: https://learn.adafruit.com/adafruit-sgp40/overview
Everything is mostly working fine, but my idea was to put the esp32 to deep sleep after each reading (the project should run on battery). Unfortunately the SGP40 seems to only give stable readings if it is constantly powered, so deep sleep doesn't work.
Is there a better sensor for that purpose?
Adafruit SGP40 Air Quality Sensor
No need to stick your nose into a carton of milk anymore, you can build a digital nose with the SGP40 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing so you don't have to manage the heater and analog reading of a MOX sensor. It combines multiple metal-oxide sensing and heating elements on one chip to provide more detailed air quality signals.
