This project connects an Arduino Uno to a Raspberry Pi 5 homelab and exposes DHT11 sensor readings as Prometheus metrics. The Arduino reads temperature and humidity from a DHT11 sensor and sends the ...

These are some great DIY projects that you can do for cheap.

Abstract: This work reports a flexible and disposable high-performance humidity sensor using the poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS) and graphene oxide (GO) ...

Forewarned is forearmed.

Compared to the Arduino Uno of old, modern microcontrollers are absolutely tiny — especially for the amount of processing power and I/O you get. But if you need something really small, like ...
