I've been selling pH, ORP, and temperature sensors for MCUs (in practice, most users use it with Raspberry Pi) for a few months. Not enough for a significant income, but fun, and I hope to expand it with the addition of a standalone, multi-sensor device soon. Great experience learning, and communicating with customers, even though the profit isn't there. https://www.anyleaf.org/ https://www.anyleaf.org/
