Turning a Kids' Electronic Kit into a Climate Sensor: My Experience with Z-Uno G2

Hello everyone! I wanted to share a recent DIY project experience I had with my son and am looking for some advice on further development.

I recently bought my son an electronic constructor kit - it’s a Christmas tree toy based on the Z-Uno G2 microcontroller (product link). I chose it due to my interest in the Z-Uno G2 itself, as I already use ZWaveJS with a UZB stick for my smart home.

My son and I successfully assembled the device, and it inspired me to experiment further. Now, I’m thinking of turning it into a climate sensor. I found this module on the internet (Aliexpress link), based on CCS811 and HDC1080 sensors.

I have a few questions for the community:

  1. Has anyone used these sensors or the module in their battery-powered projects? I’m interested in how energy-efficient they are and whether they are suitable for long-term battery use.

  2. Does anyone have experience in building home weather stations on batteries? What sensors would you recommend for such a project?

I’d appreciate any advice or recommendations! Thank you!
