Sensors and Detectors

An enjoyable and instructive project that teaches you fundamental electronics, programming and sensor integration in making a water level sensor with an Arduino Uno. This tutorial will show you how to build a working water level sensor using the widely used Arduino platform, whether your goal is to avoid overflow, monitor water levels in tanks, […]

This Arduino Temperature Controller Circuit article shows how to assemble a basic temperature controller by using an Arduino UNO board, an LCD display, a DC fan, a transistor, a DHT11 temperature and humidity sensor, and a few resistors. This circuit will allow us to display changes in both temperature and fan speed on a LCD […]

If we want to know how hot and humid it is, we can use an Arduino, a sensor called DHT11, a resistor and a LCD display to show the numbers. The DHT11 sensor will measure the temperature in degrees Celsius and the humidity as a percentage. The Arduino will understand the sensor and show the […]

Ultrasonic sensors use high-frequency sound waves to detect distance, then they measure the time it takes for the echoes to bounce back. When combined with the Arduino microcontrollers computing capacity, we can build a system that can precisely calculate an objects distance from us. This assignment will examine the fundamentals of ultrasonic sensors, the necessary […]

The LPG gas leakage detector is an essential safety tool that may stop incidents and tragedies. An Arduino microcontroller is used in this project to track the amount of LPG gas in the surrounding air. People are instantly alerted to the possible risk when the gadget sounds a buzzer and shows a warning on an […]
