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 ...

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 ...

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 ...

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 ...

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 ...
