We used Ultrasonic sensor in many of our application to measure the distance: Arduino & Ultrasonic Sensor Based Distance Measurement; Measure Distance using Raspberry Pi and HCSR04 Ultrasonic Sensor; ...

PEPPERL+FUCHS R200 series photoelectric distance sensors use Pulse Ranging Technology (PRT) for precise distance measurement up to 60m. Device achieves a repeat accuracy of ≤ 3 mm, based on ...

In recent years, with the rapid advancement of unmanned systems, particularly unmanned aerial vehicles and autonomous vehicles, the accurate collection of external information has become essential. In ...

This time measurement helps calculate the distance between the sensor and the object. Ultrasonic sensors are widely used in applications such as distance measurement, object detection, liquid level ...

After having used many of them throughout our lives, it is now time for us to attempt to build one. In this project, we will be making a distance measuring wheel using a rotary encoder that can help ...

Of course the problem is that the sensor raw data may be as low as 400 counts per inch, and when moving slowly, let’s say an inch a minute, you only get a blip up every 150 milliseconds.

Sensor Sense: Measuring rpms Feb. 9, 2006 The monitoring of rotation can involve such sensor types as proximity, photoelectric, resolvers, encoders, and tachometer generators.
