I'd like to kindly ask the forum for some ideas on my project. Perhaps some of you here have an idea or have seen a similar issue before.
I've been converting a 19" server rack into an enclosure for my Ender 3. All electronics are housed behind a separator, including a Raspi running Octoprint. Relays control the lights and the PSU. I'd like to have some safety features, like smoke detection and temperature monitoring for both the electronics and the printer compartments. I'd also like to have a means to control some of the relays using hardware.
The MH MQ sensors and a thermistor are complicated to set up on the Raspi. I know there are smoke detector/relay hacks, but perhaps my alternative solution
Here is my idea: use an Arduino and interface it to the Raspi! I could hook up the relays and the sensors to the Arduino much easier. The relays could be controlled by an IR remote control. The Raspi would read the sensor values and send commands to control the relays (ideally over serial).
Any thoughts? Thanks!
