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.

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

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

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

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

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

Water quality, anywhere, anytime!

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!

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.

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

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

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 ...

Sunglasses that serve an even more useful purpose than protecting the eyes of the blind. They can help them detect objects in front of them.

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

Take readings from the DHT11 Temperature/Humidity sensor and see them from the Arduino IDE Serial Monitor.

Easy to build, but comparable with professional seismometers, homemade Arduino seismometer.

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

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

This is a simple and fun project with pocket friendly budget.

A basic introduction to the low cost and accurate HC-SR04!

Soil moisture sensor which gives you LCD display of percentage of moisture.

This project detects the various obstacles and plots them on a graph.
