of the Arduino. Here is the test code that indicates the soil wet/dry conditions using just two LEDs (green & red). int GLED= 13; // Wet Indicator at Digital PIN D13 int RLED= 12; // Dry Indicator at ...

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 ...

It’s done by monitoring conditions like temperature and humidity ... [934Virginia’s] Arduino library to compare the difference between your target climate and actual sensor readings in ...

Stick the sensor it in the ground, and it gathers all sorts of information—things like ambient temperature, humidity, light intensity and soil electrical properties—which gets simplified ...
