Seeed Distance Sensors Selection Guide

We have released various types of Distance sensors in the recent years. You may find it difficult to make a choice between them. We feel your pain and let's take a close look at them and workout which one is best suited for you!

For all the Distance sensors in our bazaar, please click Bazaar Distance tag to check.

What is a distance sensor

A distance sensor uses ultrasonic or laser to measure the distance among objects. It is mainly used to gauge the law of the position of a moving object with time, and it can be used to complete a variety of kinematics and dynamics measurements. The main products are mobile phone distance sensors, long-distance measurement sensors and etc., which are also used in smart belts or even tracking aircrafts.

ELEM-DP 10k (diode pump)

Thanks to its diode-pumped ERBUM: the high efficiency of glass solid-state lasers, the ELEM-DP 10k laser rangefinder module provides a continuous high pulse repetition rate of 10 Hz or 20 Hz. This feature makes this compact laser rangefinder ideal for measuring or tracking the distance of fast moving objects such as aircrafts.

How does a distance sensor work

The distance detects the amount of physical changes (time difference, angle difference, pulse speed and etc.) of an object using various elements and converts the amount of changes into a distance to measure the distance and displacement from the sensor to the object.

Field of Applications

There are a numerous use of these distance sensors. Particularly, using these kinds of sensors, human beings can be monitored and benifitted or even saved from different conditions. Therefore the distance sensors play important roles in various sectors, which include daily life, industry, medical, military and etc.

Field of application Content
Daily Life The distance sensors are generally located on both sides of the handset or in the groove of the handset. When the user is answering or making a call, the mobile phone is close to the head, and the distance sensor can measure the distance between them to a certain extent, then notify the screen backlight to turn off, and turn on the backlight again when taken away, which is more convenient for the user Save more power.
Industry Railway contact network measurement; Building limit measurement; Measurement of unsuitable objects; Industrial automation and production intelligent management; Automobile speed and flow statistics; Industrial monitoring signal trigger control; XY positioning of tower crane; Monitoring of ship's safe docking position; Container positioning; Overhead cable measurement, Height limitation measurement; Measure the width of the box on the conveyor belt.
Medical treatment Rope displacement sensor for remote surgical tool positioning and bed positioning in X-ray / CT scan.
Military Mostly used in field environment (mountain conditions, canyon depth and etc.), aircraft height detection and some are used for mine depth and material height measurement. While aircraft height measurement is mainly utilized to detect the height from the ground when taking off and landing, real-time displayed on the control panel.
