a soil moisture sensor for raspberry pi

Soil Sensor

This repo has three things:

1. Code for a Raspberry Pi to read soil moisture levels based on capacitance measurement of the soil.
2. A flask app to display the sensor data on a webpage.
3. A shell script to execute the sensor code (need to update the paths based on your system).

The sensor code must be ran as a cron job on the RPi.

I'm saving my work without refactoring or writing much documentation, so anybody who tries to use this repo might have a hard time (myself included)!

hardware

• breadboard
• jumper cables
