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

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

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

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

Use HC-SR04 on Arduino with Processing

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

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.
