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

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!

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.

Smarter Home Energy Use with Open Source and Cheap Sensors.

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

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

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

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

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!

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

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!

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

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

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

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

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

It is hard to measure the height of the children. So, we made Height Measure using distance sensor VL53L0X.
