+ LCD/OLED can be used to measure body temperature or to detect movement... in Celsius and Fahrenheit!
In this tutorial, you will learn how to use a soil moisture sensor. Practical examples are also provided to help you master the code.
In this tutorial, you will learn how to calibrate and use MQ9 gas sensor with an Arduino board.
Learn how to use a PIR motion sensor to detect movement. You will also learn how PIR motion sensors work and how to use them.
This little project will show you how to use a soil moisture sensor.

This project will show you how to use temperature and hmidity (DHT11 and DHT22) sensors with an Arduino card.
My project helps visually challenged people to walk without crashing into walls and obstacles. This help them to live freely without taking
If there will be no traffic on the other signal, one shouldn’t wait for that signal. System will skip that signal and will move on next one.

I found limited documentation on the usage of a color sensor I recently purchased, so here is my attempt to make it more simple.
Ultra low-cost flow-through photometer for on-line measurements of bacterial density.
by Alex Kutschera
A standard speaker can be used to detect vibrations and send data to a microcontroller.
This project allows you to draw your own controller to be used with anything. It utilizes capacitive sensing and graphite's conductivity.
Using ultrasonic sensors to measure distance of obstacles, taking into account temperature and humidity that affect the speed of sound.
