I am contemplating connecting an Argon to this device – Adafruit MiCS5524 CO, Alcohol and VOC Gas Sensor Breakout : ID 3199 : $14.95 : Adafruit Industries, Unique & fun DIY electronics and kits. I gather I can just get 5V from the Argon, and read the analog voltage. But the documentation says that “All GPIOs are only rated at 3.3VDC max.” So, does this mean that I’ll need extra hardware to be able to safely connect this? I found a discussion from 2018, but that was for the Photon, so I thought I’d check here before frying my Argon.
hey, I played with a 5v sensor and I did it like I wrote in this write up.
maybe you can take a look?
look at Sensor adjustment to 3v3
