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

Use HC-SR04 on Arduino with Processing

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

We built a stylish and useful humidity and temperature sensor for our home workshop that uses color to alert us to big swings in humidity.

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

Track ME is a "small" GPS, SD Card, and GSM Shield controlled by an Arduino Mega. Call me and get my location.

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

The ESP system make it easy to recognize gestures you make using an accelerometer.

Let us predict the changes around us with Arduino

A digital finger sensor to protect against theft.

BrewBench - Is an Arduino home brewing kettle temperature monitor, controller and notification system. It can work as a RIMS system.

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

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.

LIDAR stands for Light Detection and Ranging. LIDAR is used for many applications including 3D scanning, mapping, laser guidance, etc.

Anemometer or a wind speed measuring device is a common weather station instrument. It was costly online, so I built one!

Many fun environmental sensors need a hardware interrupt. With the MKR1000, you no longer need to choose! You get I2C, analog ins too!

I built an Arduino Weather Station. It uses a DHT 11 (it will also work with DHT21 DHT22).

A method in which waste management is automated. An innovative system that will help keep the city clean and healthy

An Android app-controlled, Arduino-based kit that receives and analyzes humidity and temperature data.

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

We connect a VL53L0X Laser time-of-flight sensor to an Arduino to measure the liquid level in a tank using ToF ranging.

This project is about control of temperature in values of 23 and 25 grades and control for hysteresis using DHT22 and Arduino 101.

Low maintenance, high output air pollution, sound pollution that put throughout the city without wiring.

Water quality data monitoring for swimming pools, fish aquarium and more!
