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 ...

When the sensor detects that the moisture content is already below 30%, it sends a signal to the Arduino, which, in turn, activates a water pump to provide hydration to the plant.

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

My shed is mostly done, which means I'm moving onto other projects that look a lot like landscaping. Lawns, gardens, etc. I want to be efficient in my watering, and potentially even lazy and have ...

This weekend’s Make project is a great one for pet owners — an automatic water bowl refilling device! It’s a fairly simple build, utilizing an old water jug, an Arduino, an aquarium pump ...

We're drowning in technologies to clean water. But which ones are the best?
