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 ...

What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting real-time data on soil moisture, temperature, and sunlight. From sensor calibration ...

This Water Level Indicator is a small and very useful mechanism to find the water level in an overhead tank or in any other water container. This is possible by using a set of 9 probes which are ...

Most of us come across water overflowing from overhead tanks at homes and offices. While many of us stop with worrying about the wastage of the precious liquid and wastage of energy, a few think of ...

This book is about using both the Raspberry Pi 4 and the Arduino Uno in PID-based automatic control applications. The book starts with basic theory of the control systems and feedback control. Working ...
