From the project

DIY and open source soil moisture sensor 🪴

Low-power capacitive soil moisture sensor with BLE connectivity.

powered via CR2032 coin battery transmits telemetry via BLE measures ambient light and temperature visual indication via LED

Top | Bottom :-------------------------:|:-------------------------: |

This sensor determines the amount of soil moisture by measuring changes in capacitance of the probe submerged in soil.\ Insertable part forms a parasitic coplanar capacitor which uses soil as a dielectric medium.\ As the environment around the capacitor changes depending on whether the soil becomes wetter or drier, so does it…
