We are showing how to use DS18B20 one wire water proof temperature sensor using Arduino.

This video will illustrate the working principle of the Water Quality Monitoring and Notification System.

Weigh objects, and make decisions based on weight.

Track your face using OpenCV's facial recognition.

A beginner-tier project I hope will help the fellows that are newbies in the Arduino world!

This project detects the various obstacles and plots them on a graph.

Very basic and quick usage of a water sensor.

Long-range wireless sensor based on Whisper Node capable of running for over a year on a single CR2032, transmitting data every 60 seconds.

This is a temperature tensor that is made using an Arduino UNO and an LM35 sensor which measures the temperature of a given area.

This parking sensor with Arduino is an easy project.

A simple Electromagnetic Field Detector.

A project that displays the temperature and humidity of a room on your mobile in real time.

This project uses an ultrasonic sensor to "sense" if the door opens or closes.

Basic instructions on building a simple auto fan.

It measures the distance between you and the place where you point it to. Hope you'll enjoy it!

In this project, use the YF-S201 1/2-inch water flow sensor to measure the water flow rate (L/min) and display it on an LCD.

On the display is printed temperature (celsius) and humidity (%) with a DHT11. When it's raining the LED lights up. You need a rain sensor!

The Grove Gas Sensor (MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4 and CO.

Reads and stores in SD card, the temperature and humidity values over time.

A system using combination of an Aruino, several sensors and controlled via a ESP8266.

First version of basic Home Weather Station.

Obstacle distance is measured using ultrasonic sensor and Arduino. The data is processed using Processing and the distance is marked.

CO2 monitor and log based on MQ-135 with temperature and relative humidity correction.

An easy project using stuff from the starter kit: Arduino Uno, temperature sensor, 16x2 LCD display, some LEDs and a Piezo.
