Merry Microchips! — 2025 Holidays Competition Discussion Thread

I am thinking of making a solar powered smart pot. There are lots of cheap chinese models already available. But most of them requires continuous power supply. My last year project was an absolute drain on power. So I'm looking for some low power mcu with small form factor, small e-ink display. I already have a small i2c based load sensor which can be used to alert when water level is low. I only need to worry about water proofing the circuit.

Good project idea. How reliable is the load sensor to indicate water level, as the plant grows it hopefully gains mass ? Just curious if your plant is decorative or provides herbs or fruit ? 

This is the sensor family I'll be using.

This is indented to be a small indoor plant (but placed at window side of course) that doesn't grow up fast.

Thanks. One way I learn what sensors are avaliable is seeing what other folks use. There are literally thousands of sensors and modules. 

I wish there were an occasional "shopping cart" available as a prize. I would order a family of sensors to have in hand for impromptu projects.

I'm always very open to prize suggestions, if you have a family of sensors in mind then let me know and I can potentially make that a future prize option.

I can help with that idea, maybe various new sensors packaged with a SoC.  :-)  and a smattering of very useful interfacing parts.
