Description

The teeniest tiniest little weather station!

Designed to hold a Wemos D1 mini lite, a generic BMP280, and a generic 128x32 oled display to make a super tiny weather station. I've included sample source code, but you'll need to adapt it, at least by adding your credentials, to use it.

The code is designed to operate with the QNAP QIOT system, but can easily be adapted to transmit data to other platforms.

Here are the components I used to put it together:

Note: The flat back of the V1 will work better then the V3 - they moved the USB chip onto the back and it won't sit as flush inside.

(yes, all those links are 2 or 3 packs, but it's so much cheaper that way. BOM is less than $10 each, not including filament)

You'll also need some fine hook up wire (and soldering skills). I really like this stuff for low-draw work like this: https://www.amazon.com/HiLetgo-Development-ESP8285-Wireless-Internet/dp/B07BK435ZW/ref=as_li_ss_tl?keywords=wemos+d1+mini+lite&qid=1577740657&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExVDVKVjFJSjU1NkEmZW5jcnlwdGVkSWQ9QTAyOTI1MDlVVkY0UFNYOUdSV0smZW5jcnlwdGVkQWRJZD1BMDQwNjgxMjMxTzVVSDdGUE40Nk4md2lkZ2V0TmFtZT1zcF9hdGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl&linkCode=sl1&tag=mobile0fca077-20&linkId=ad5f7cfa5d57b53bfdfd822fd4fde329&language=en_US

One roll lasts me about 2 years.
