Here we use PIR sensor and Arduino to detect the motion of a hand. This detection can be used to operate electronic equipment.

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

Generates maps based on distance between itself and obstacles autonomously and provides visual feedback.

It is a device that measures CO2 levels, inside and outside temperatures, and humidity.

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

This video will illustrate the working principle of the Water Quality Monitoring and Notification System.

Use the DHT Temperature Sensors in C# code via a C++ Windows Runtime Component to implement a one-wire protocol on Windows 10 and the RPI2.

UltrasonicEyes is a fun and quirky project you can place somewhere and watch as it looks at things moving around in front of it. Freaky!

Someone has been eating my cookies! Thankfully Arduino is here to help find out who it is.

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

Dear friends welcome to another tutorial! Today we are going to build an interesting Arduino project which is using a fingerprint sensor ...

Water quality, anywhere, anytime!

This is the first generation of my Arduino based mini-weather station with Wi-Fi connection, which is able to post data publicly online.

Long-range wireless sensor based on Whisper Node capable of running for over a year on a single CR2032, transmitting data every 60 seconds.

Short and easy, read distance 2 - 400 cm and plot it in I2C OLED screen.

Track the sun in X and Y with this simple Arduino project.

Let us predict the changes around us with Arduino

A project that displays the temperature and humidity of a room on your mobile in real time.

A remote controlled vehicle with stereo cameras on a head-tracked pan-tilt unit and wireless 3D first person control via an Oculus Rift.

Tracks compass heading, altitude, temperature, pressure, humidity, time, travel distance and GPS location during a hike.

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

We built this to help our farmer friend in Thailand track his truck to prevent rice theft.

A project that speaks on behalf of mother nature. It is real time air quality monitoring device.
