Types of Distance Sensors And how it works
Introduction: Distance sensors are devices designed to measure the distance between the sensor and an object. They find applications in various fields, including robotics, industrial automation, automotive, and consumer electronics. There are several types of distance sensors, each utilizing different principles to accurately measure distances. In this article, we will explore some common types of distance sensors and how they work. 1. Infrared (IR) Sensors: Working Principle: Infrared distance sensors emit infrared light and measure the time it takes for the emitted light to bounce back after hitting an object. The sensor calculates the distance based on the time delay. Application: IR sensors are commonly used in proximity detection and obstacle avoidance systems, such as in robotics and automation. 2. Ultrasonic Sensors: Working Principle: Ultrasonic distance sensors use ultrasonic waves (sound waves with frequencies above the human audible range). The sensor emits ultrasonic...
