The two main electrical components of this design are an Arduino Uno R3 and a water level sensor. To connect the sensor to the Arduino, 3 wires are needed: Power Supply: Connect the VCC pin of the ...

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 ...

This project demonstrates a water level monitoring system using an ultrasonic sensor and an Arduino. The system measures the water level in a container based on input voltage and displays the height ...

Whether you're a new plant parent or have been tending to an expansive collection for years, chances are you struggle to keep up with a regular watering schedule. Oftentimes, it isn't as ...

Instructables member Qttting_F has published a fantastic project detailing how to build a Water Surface Lamp, using a little Arduino coding and hardware, combined with a few LED lights to great effect ...

The itch to investigate lurks within all us hackers. Sometimes, you just have to pull something apart to learn how it works. [Stephen Crosby] found himself doing just that when he got his hands on a ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

Tilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, ...
