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

Professional quality wireless weather station.

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!

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

An automated humidor using an Arduino — with or without building your own humidor.

This project consists of a set of proximity sensors with a haptic interface to alert the user to the presence of objects around them.

Kayaking GPS: speed, time, latitude, longitude, distance and azimuth to waypoints, odometer, tide clock, battery monitoring.

Use the cheap Fiagro TGS4161 Sensor to monitor CO2

A cube with all the necessary sensors, suitable for a wide range of applications like agriculture. Know the land beneath you!

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.

Let us predict the changes around us with Arduino

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

I’m on a mission to reduce the amount of noise my LulzBot Mini 3D printer makes. The stock fan is loud and it's either on or ON!

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

FSM that allows to identify the direction of the object.

This project is about a simple movement detector. Whenever any obstacle comes in a line (predefined) a light will glow.

A tech high-school student-teacher team from Uruguay developing High Altitude Balloons for science! IN ACTIVE DEVELOPMENT!

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!

Get the weather information through an Android app constantly and use the solar energy generating by the PV panel to charge devices.

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.

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