In this tutorial, we will learn how to detect Smoke and inflammable gases using an MQ-2 sensor.

In this protip, I will show you how to build DS18B20 Digital Thermometer with Arduino.

Did you know that a standard three-wire PC Fan can be used as a sensor?

This project allows you to draw your own controller to be used with anything. It utilizes capacitive sensing and graphite's conductivity.

This system monitors the moisture of soil and waters it by 5v DC motor based water pump when needed.

Make a Ultrasonic Range Detector Using Arduino and SR-04F to measure any distance without using rulers with this simple tutorial.

This project will show how to set up a 16 x 2 LCD screen and display multiple sensor values.

This little project will show you how to use a soil moisture sensor.

Need your project to gauge distance? Here's your module!

This project will show you how to use temperature and hmidity (DHT11 and DHT22) sensors with an Arduino card.

Using ultrasonic sensors to measure distance of obstacles, taking into account temperature and humidity that affect the speed of sound.

Just before creating my next tutorial, which will be using a PIR sensor, I thought I might create a separate tutorial for PIR Sensor.

This project is an Arduino radar. It is a simulation of a radar.

I found limited documentation on the usage of a color sensor I recently purchased, so here is my attempt to make it more simple.

In this tutorial, you will learn how to use a soil moisture sensor. Practical examples are also provided to help you master the code.

Code and explanation for getting directional and motion data from the raw sensor outputs.

If there will be no traffic on the other signal, one shouldn’t wait for that signal. System will skip that signal and will move on next one.

A system to maintain the pH level of a sample within a defined range.

+ LCD/OLED can be used to measure body temperature or to detect movement... in Celsius and Fahrenheit!

The Arduino 9 Axes Motion Shield allows your Arduino to measure movement: orientation, acceleration and magnetic field.

Replace the PIR motion sensor with this module and it's 360° detection angle baby!

Connect Infrared Obstacle Avoidance Sensor to Arduino Nano and program it to detect obstacles - Quick and Easy!

Connect multiple OneWire Maxim DS1820/DS18S20/DS18B20 thermometers to Arduino, and program it to measure the temperatures - Quick and Easy!

An IoT device to automatically switch on/off electronic appliances based on the availability of human beings, especially in public services.
