Chose ESP32-C3 Seeed XIAO for MCU since I use XIAO for everything. DHT11 for temp and humidity info to estimate the speed of sound for the ultrasonic distance sensor.

The PCB was made as small as possible because why make a PCB bigger than it should be.

First, I designed the case for the PCB. Just the PCB.

Then, I decided I should work on the case for the ultrasonic sensor. I took inspiration from [this]https://grabcad.com/library/simple-cover-for-hcsr04-sensor-1(https://grabcad.com/library/simple-cover-for-hcsr04-sensor-1), and started designing my case for the ultrasonic sensor.

Finally, the logical thing to do was to add everything together, and make the final assembly. This was also the first time I made an exploded view.

I was only able to use my phone to do this, so I had to learn how to use onshape on mobile. I didn\'t do much, but i fixed some of the formatting of the parts so i could export them. this was mostly just grouping parts that should be grouped together, but it was also an opportunity to learn how to actually use onshape mobile ideally, not waste dozens of minutes on trying every button until one of them did what i wanted them to. after this, i just exported everything and sent it to my computer (once i was able to use it). on my computer, i just committed everything normally, and didn't waste that much time.

I added the screenshots for PCB, Schematics and CAD to the README.md, and also added a BOM.

Writing firmware is hard. Especially when you don't have the microcontroller or even something similar to the one you're using.

Writing code is hard. Especially when you decided to use vanilla html, js and css. i chose to use vanilla js because its very light weight and adds a whole zero bytes to my build size (im not even buliding anything) I decided to use the vanilla canvas api. note to self: dont use the vanilla canvas api next time.
