How to Set Up an Ultrasonic Range Finder on an Arduino

Ultrasonic range finders measure the distance of objects from the sensor using sound waves. The HC-SR04 is the most common ultrasonic range finder used with the Arduino.

In this video, we will first build a minimal parts distance sensor with the Arduino, then we will build a more accurate distance sensor by including temperature measurements into the distance calculation. Then we will build a highly accurate distance sensor using temperature and humidity data taken from a DHT11.

The ultrasonic range finder can be purchased here:
