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

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.

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

Smarter Home Energy Use with Open Source and Cheap Sensors.

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

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

Let us predict the changes around us with Arduino

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

We can measure body temperature without contact with this device.

Pulse induction metal detector, built on the Arduino Nano.

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!

A cheap DIY air quality monitoring device.

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

Follow this project to make an infrared thermometer by yourself!

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!

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

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

This project will demonstrate how to build a water level monitor using an Arduino Nano, a Solu SL067 water level sensor, and an indicator.

Arduino Nano and Visuino: Plot BME280 Temperature, Humidity and Pressure on Nextion Display Scope - Quick and Easy

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

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

Simple data logger that stores electrical data (voltage, current, power, energy, etc.) in an SD card, with timestamp for later analysis.

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