Add Temp and humidity sensor to mk4  

RE: Add Temp and humidity sensor to mk4

I'm pretty sure there isn't but I'm also wondering about the purpose?

...it wouldn't be too hard to power a module from the usb but like @fuchsr I'm wondering what you are trying to acheive..?

Cheerio,

RE: Add Temp and humidity sensor to mk4

I use a home made cabinate to heat the chamber as I print mostly with PC and ASA (98%) so I need to monitor the temperature & humidity.

RE: Add Temp and humidity sensor to mk4

I have uptill now used a Raspberry Pi to provide temp, humidity & camera + network control - I guess I still need to keep the Raspberry Pi going and just use Mk4 network as it allows

RE:

I just use a super-cheap mini fridge thermometer off Amazon for this purpose. Which of course won't do if you want remote monitoring.

RE: Add Temp and humidity sensor to mk4

For remote monitoring, one could couple a NodeMCU with a simple temp/humidity sensor and monitor it with Home Assistant.

Still, it would be a nice gadget if Prusa provided an upgrade Module the measurements of which would be integrated in PrusaLink. Not a necessary mod, but one I'd buy anyway. 😉

The printer itself may be the wrong place to monitor this, the microclimate it generates would obscure the actual environment values.

Cheerio,

I have one of these in each of my enclosures and filament dryers. it is a Xiaomi Mijia Bluetooth thermo-/hygrometer. They cost around 5 € on Ali and are running on battery (CR2032). One battery lasts well over a year. They are accurate enough for my purposes and you can calibrate them via the firmware flash interface to another sensor that you trust. You can flash the BTHome firmware on them and then they are cloud-free and can easily be integrated via a Bluetooth Proxy into ESPHome and Home Assistant if you have that already. There you can do data logging and grafana the hell out of the data if you want 🙂
No idea why the text above is bold, sorry.
