This post is some free-ish form notes about a project that is either work in progress or complete.
This project is a small sensor to monitor Temperature, Humidity, and Light levels. The project may end up in a toy Star Trek TNG Tricorder case at some point in the future, but I wanted to document where it is at a today. Originally I used an Adafruit Huzzah (ESP12) board, but after I determined I wasn’t going to use the wifi, I switched to the Adafruit Adalogger board. This board has many more analog channels which could be of use for other sensors in the future.
The choice of resistors and the MINLIGHT and MAXLIGHT values will vary depending on the board in use.
- Adafruit Feather M0 Adalogger
- AM2302 (eBay)
- Monochrome 0.96″ 128×64 OLED graphic display
- Photo Resistor
