If your Arduino soil moisture sensor isn't working, check these common issues: verify all wire connections are secure, ensure you're using the correct Arduino pins (A0 for analog, digital pin for ...

Simply connect the Sensor's output to any digital pin on the Arduino and check for a high pulse; if the Arduino reads a high pulse, Gas has been detected; if the Arduino reads a low pulse, no Gas is ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

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 ...
