When your residence has soil moisture sensors embedded that were dictated by your friendly neighborhood HoA, you may start asking questions about the system used.

To build this soil indicator system, we have used LCD I2C along with electronic components Arduino Nano, Soil Moisture Sensor, Bread Board, Arduino Nano Cable, Jar filled with soil.

But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how capacitive soil moisture sensors work simply, clearly, and concisely.

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

About I have used a soil moisture sensor with ESP32 to build an iot based moisture monitoring system where the soil moisture will be displayed in adafruit dashboard in the form of graphs as well as on ...

As such, I'd like to build myself some wireless moisture sensors for moderate scale production (consider 50 test points reasonable).
