The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

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 ... in the dry soil and measure the resistance value and ...

What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting ...

I've got an Arduino/Bluetooth (Bluetooth Bee-Standalone). I've hooked it up with an HC-SR04, it's intended to be mounted at the top of a rain barrel to measure the water depth. What's the best ...

Once you have the water level then you'd know to turn ... I got my float sensors in today and have it connected to an arduino uno. Easy enough to read the value and seems to work just fine.

The first is an LED matrix that eleven-year-old Daniyal brought to life using Arduino. In the video ... Haya and Taha built a water level sensor. Watching their video (you’ll need to crank ...
