Etäisyysanturit, or distance sensors, are devices used to measure the distance between an object and the sensor. They are widely used in various applications, including robotics, automotive, industrial automation, and consumer electronics. There are several types of distance sensors, each with its own operating principles and suitable applications.

Ultrasonic sensors are one of the most common types. They work by emitting ultrasonic waves and measuring the time it takes for the waves to bounce back after hitting an object. This time is then converted into a distance measurement. Ultrasonic sensors are known for their accuracy and reliability in measuring distances up to several meters.

Infrared (IR) sensors, on the other hand, use infrared light to measure distance. They emit IR light and measure the time it takes for the light to reflect back from an object. IR sensors are often used in short-range applications due to their limited range and sensitivity to ambient light.

Laser sensors use laser light to measure distance. They are highly accurate and can measure distances with high precision. Laser sensors are commonly used in applications requiring high accuracy, such as in industrial automation and automotive.

Time-of-Flight (ToF) sensors use the time it takes for light to travel to an object and back to measure distance. They are known for their high accuracy and ability to measure distances in real-time. ToF sensors are used in various applications, including gesture recognition and 3D imaging.

Capacitive sensors measure distance by detecting changes in capacitance. They are often used in touch-sensitive applications, such as touchscreens and proximity sensors.

Each type of distance sensor has its own advantages and limitations, making them suitable for different applications. The choice of sensor depends on factors such as required accuracy, range, and environmental conditions.
