Introduction Recently I’ve made a poor guy 3d printer enclosure, But I don’t have confident to leave the room while the printer is working, I need to keep my eyes on it, So to make the solution more practical I’ve decided to rig a very basic system to monitor humidity and temperature just to take action whenever the temperature go out of normal, I also wanted to be able to switch light and camera on an off remotely which mean a WiFi capability is a must, and because the best system is the one you already have, I finally found a good use for my Raspberry pi 4, only needed ESP32-CAM and some sensors.
