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

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

In this tutorial I am going to show you how to build a Wireless Weather Station with a big 3.2" Color TFT display using Arduino.

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!

Smarter Home Energy Use with Open Source and Cheap Sensors.

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

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

This device measures fine dust and NO2 concentration in the air while on the move and adds GPS coordinates to each measurement location.

Let us predict the changes around us with Arduino

With only an arduino board, two servos, and an hc-sr04, and some python, you can create a room scanner that is capable of showing depth!

We can measure body temperature without contact with this device.

A super smart buoy with lots of sensors that sends data over radio to a base station where it is displayed on a real-time dashboard!

Follow this project to make an infrared thermometer by yourself!

Intelligently reduce the moisture in your basement/crawlspace to help control mildew growth and lower your heating/cooling bill.

This is a very precise scale for any weight up to 1.5 kg!

Senses for smoke in the air near a 3D printer and will sound an alarm and turn off power to the printer if smoke is detected.

In This Tutorial, I will Show You How to Make an Arduino Based MPPT Charge Controller

An Arduino based device to monitor the levels of combustible gases, carbon monoxide, relative humidity and temperature in the kitchen.

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

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

Pulse induction metal detector, built on the Arduino Nano.

A cheap DIY air quality monitoring device.

The detector can detect a small metal coin at a distance of 15 centimeters.

Connect GPS and MicroSD Card to Arduino and log the GPS information - Quick and Easy
