In this crafting recipe I will show you how to make your own room meteostation (almost) from scratch. Without any 3D-printers or laser cutters!

It features CO2, humidity and temperature sensors, built in web server with settings and live charts, automatic constant readings logging (every 5 seconds), color indication for low/high levels of readings and sound alarm for high CO2 level with ability to set any monotonic melody you want.

As I tried to fulfill this “true DIY” philosophy of making as much as possible myself, I had to learn many new things and develop non-existent skills. I hope this instructable will motivate you to do the same! I should mention that this is actually my first Raspberry Pi project, and I had almost 0 experience with Linux OS (I only programmed on Windows so far). So I hope I didn’t failed too much in the eyes of experience Raspberian people!

Without further ado, lets get to the supplies and costs. A couple of notes here. “My price” is actual cost of all the parts I purchased. It’s higher than on Aliexpress or other stores, because its local electronics store and they have higher prices (I chose it for more reliable delivery). Also note that its hard to find some parts individually or in small quantities like 2x5 mm self tapping screws, for example. I ordered 100 g of them, 971 to be exact, but I still only included price of 8 that where used. Same thing with tools, because you can use tool for potentially unlimited amount of projects in future, it would be not right to include it’s full price in the final cost of a device. Besides, some of you might have most of the tools already. I salvaged buzzer from annoying UPS unit, so I didn’t had to buy it.
