I haven’t posted about soil moisture sensors in ages, but I’ve completed a number of iterations and I thought it’d be fun to look over the evolution of the hardware. My goal has been to build a small, low power, inexpensive device, that I can place in indoor and outdoor plants to collect soil moisture, light, and …
