It would be really neat if someone made a sensor that could tell you whether your plant needs to be watered.

Yeah, I've messed around with water sensors before. I just thought it would be neat to measure it via stress on the plant itself.

An RPI to measure moisture seems complete overkill. There'sESP Home for small sensors https://www.instructables.com/Building-a-Wireless-Soil-Moisture-Sensor-With-ESPH/

Pi picos are pretty good for iot projects like that. ESP are more power efficient, but a pi can be more self sufficient. I think it depends on the project.

The linked project recommended a Pi3 though.

Ah, that's just overkill.
