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 ...

It runs on an Arduino MEGA 2560 PRO (or similar microcontroller) and supports a wide array of additional hardware including pressure transducer, water level sensor, flow meter, OLED display ...

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.

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 ...

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 ...

Dome angle, liquid characteristics and floor repellence combine to make the water sit in a ring around the edge if the sensor is level, and in a crescent around the walls if the sensor is anything ...
