Here are the readings so far from 07/07/2026 to today 07/11/2026.
There will be a few momentary blips in the data because now and then I have to restart my PC for some stupid reasons. In an ideal world, I’d have a dedicated Raspberry Pi (or even a special computer) designed to specifically capture this data. But, time constraints mean that I’m doing the best I can with what I have. I ordered some AHT10 boards to connect to the Wemos W600 boards (since this board doesn’t have an analog input) I have lying around – only to discover that the Wemos W600 boards are basically abandoned/unsupported and just won’t detect anything coming out of those sensor boards. I then tried some Wemos D1 Mini boards… and no dice there either.
I think the lesson might be… Just get more of the boards that I know will work. These days, that means the Adafruit QtPy boards and the SeeedStudio XIAO ESP32 line. They’re small and at $5-$8, I’ll save WAY more time than if I was trying to get a $2 board working. I guess it could be that the sensor boards are junk – but I won’t really know until I dig into these deeper and that’s not going to happen until the weekend.
I was inspired to start testing this stuff by a local science fair put on by our local utility company. But, let’s not kid ourselves, I’m only too happy to dive into a project like this. Rather than having a bunch of wires from one single ESP32 board going to three different locations in the house, I’d like to ideally have three remote sensors that are battery operated and I could place throughout the house. In a move that may well bite me in the backside, I’m trying to use a Wemos D1 Mini for these remote sensors. I already have them lying around, can run Micropython, and can connect to the I2C / AHT10 sensors I purchased. Rather than scrapping the existing system, I’m going to see if I can build up the new system in parallel, get it running, then disconnect the old system.
While I’ve shopped around for some window screens, I haven’t actually purchased one yet. However, I still have about 2 weeks to go before the science fair, so hopefully I still have time to get this done. :)
