So i started a mini project, that is turning out to be not so min. i am calling it Aries (yes cause the name sounds cool 🫠 )…Its supposed to be an offline room, air quality sensor that alerts you when the air quality is really bad, or when someone farts 😂.

Today i did the rough sketch, spent a lot of time to choose the sensors and components had to use Claude to cross check somethings like pin outs and power requirements for the project, and began wiring the schematics….🙂‍↕️i’ll be posting updates and possibly a voice over as i move on with this project… so em yh.

Currently this is the plan :
XIAO ESP32-C3,
SCD40 (CO2 sensor, I2C) =>SCD40-D-R2,
Circular TFT Display 1.28 Inch TFT LCD Display,
Switch for batteryLiPo 3.7V [ 503450 3.7V 1000mAh Polymer Lithium Rechargeable Battery with JST PH2.0 Plug ]
and then a Custom PCB with the circuitry for the sensor
