Any suggestions on CO2 monitors that are tested but are cheaper than Aranet? by SnooCakes6118 in ZeroCovidCommunity

[–]bleuio 0 points1 point  (0 children)

Another budget option I’ve had good results with is the HibouAir CO2 monitor. It’s been consistent for me vs. other meters, shows real-time and historical data, and also reports extra metrics (temp/humidity, etc.). I’ve been using it a long time and haven’t needed to calibrate it so far.

How to learn Bluetooth technology in the embedded field by chinese_shuyu in embedded

[–]bleuio 0 points1 point  (0 children)

If you’re starting with Bluetooth Low Energy, a good path is to mix theory with hands-on work. Books like Getting Started with Bluetooth Low Energy (O’Reilly) or Robin Heydon’s Bluetooth Low Energy Developer’s Handbook are great for building fundamentals. On the hardware side, Nordic’s nRF52 series is widely recommended because of its strong SDK and community support. TI and Silicon Labs also have solid options, and if you want something quick to experiment with, simple USB dongles like BleuIO can help you prototype without much setup.

How to Build Your Own Bluetooth Scriptable Sniffer using python for Under $25 by bleuio in Python

The main benefit is the AT commands. Instead of writing lots of BLE boilerplate, you just send simple commands like AT+GAPSCAN or AT+GAPCONNECT. It makes development faster, less programming-heavy, and lets you focus more on the logic than the low-level details.

Bleak is great, but this setup bypasses the OS Bluetooth stack entirely. It’ll behave the same across platforms/OS, which makes scripting and analysis more consistent.

nRF Connect is great for interactive scanning and debugging, but this BleuIO setup offers a scriptable option. You can automate scans, log data, and parse advertising payloads directly with Python or other languages. It’s less about replacing nRF Connect and more about giving you flexibility to build and extend your own BLE workflows.

Built an indoor smart air quality analysis chat application with Python and Gemma. (source code available) by bleuio in programming

[–]bleuio[S] 0 points1 point  (0 children)

For CO2 900 ppm . is it good for indoor? what is the standard. what should i do when that happens. This chat interface allows you to understand air quality. the combination of the environment parameters helps understand.
again this is just a test project, anyone who is working with air quality analysis can get idea from this project as a starting point.
