This is an Arduino Uno with a DHT11 temp/humidity sensor with and LCD screen powered by a power bank.

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

In this tutorial, we will learn how to detect Smoke and inflammable gases using an MQ-2 sensor.

Real time plant monitoring system to view temperature, light exposure and moisture.

Use HC-SR04 on Arduino with Processing

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

In this protip, I will show you how to build DS18B20 Digital Thermometer with Arduino.

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

This is tutorial to help you understand ultrasonic and buzzer and go deeper into learning Arduino, follow these steps and give me feedback.

Generates maps based on distance between itself and obstacles autonomously and provides visual feedback.

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

Water quality, anywhere, anytime!

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.

It is a simple tutorial on how to create little a security device using an Arduino.

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!

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.

Use the DHT Temperature Sensors in C# code via a C++ Windows Runtime Component to implement a one-wire protocol on Windows 10 and the RPI2.

In this project, I have shown how to interface a GPS module with Arduino UNO. The data for longitude and latitude is displayed on the LCD.

Simple Temperature Monitoring with DHT22 & Arduino.

Smarter Home Energy Use with Open Source and Cheap Sensors.

This system monitors the moisture of soil and waters it by 5v DC motor based water pump when needed.

The sunflower follows the light using a servo motor and two photoresistors.

This is the first generation of my Arduino based mini-weather station with Wi-Fi connection, which is able to post data publicly online.

Did you know that a standard three-wire PC Fan can be used as a sensor?
