Top 12 Ultrasonic Proximity Sensors

Electronic devices detecting the distance of a targeted object by releasing ultrasonic sound waves and converting such reflected sounds into an electric signal are called ultra-sonic sensors. While the use of Ultrasonic sensors is consistently expanding with technology making a perfect choice can be challenging without following a proper guide.

Ultrasonic Proximity Sensors Buying Guide

Ultrasonic sensors are of two distinct types- Either Proximity sensors detecting presence or movement of objects commonly applied in automobile self-parking technology and robotic obstacle detection systems, or level sensors for level monitoring. However, proximity sensors today are used for varying applications, ranging from Android and iPhone sensing to contactless object detection and measurement. Hence, picking one that’s accurate, valid and easily connectable reliable can be difficult given the following:

Detect your Object Requirement

First things first call for detecting the object the buyer is planning to use the proximity sensor on considering factors like the nature, colour and shape, distance and material of a particular object to be detected. These objects may vary in terms of metal parts, objects made of any material, magnetic parts, or objects with reflective properties.

A ‘Techy-centric’ Approach to Selection

Technology is a vital factor while choosing ultrasonic sensors. While Inductive, Capacitive and magnetic proximity sensors are individually designed to detect metallic and non-metallic objects, Ultrasonic proximity sensors, by contrast, are used for detecting objects present in either form of solid, liquid, viscous or powdery or magnetized as well as distance sensing. Comprising of a transmitter and receiver it emits ultrasonic waves up to 40KHz which is the ideal one and an ideal detection distance range up to 2-450 cm.

An Environment of Sensing

The choice of ultrasonic proximity sensor also depends upon the environment which it will sense particularly related to moisture, temperature and cleanliness. It will be advisable for buyers to make their choice based on which environment they choose to sense. For instance, these are most suitable for sensing in harsh environments for trash level monitoring.

An Expensive or Inexpensive Choice

Though advanced ultrasonic proximity sensors are considerably more expensive often greater than $500 than basic ultrasonic sensors raging between $50-$500, they are a one-time worthy investment given their durable construction, output capability, high accuracy, and adjustable parameters providing a perfect solution for numerous non-contact measurement applications.
