Plant Moisture Monitor
Program an Arduino to tell you when your plant needs watering.
Tips for use
The following hardware is required for this project:
- An Arduino Uno (or likewise)
- A moisture sensor
- An A2D converter (comes with most moisture sensors)
- Three jumper leads (for Arduino)
In this tutorial you will program the Arduino to detect different levels of moisture and make the LED flash accordingly.
The original web version of the tutorial can be viewed here.
There is also a link at the end to a Raspberry Pi Learning Resource that shows you how to connect your program to Twitter so it can "tweet" updates about the moisture levels!
