Ultrasonic sensor is designed by ultrasonic characteristics.Ultrasonic is a kind of mechanical wave which vibration frequency is higher than the sound wave. It has high frequency and short wavelength, especially the good direction, Which can transmit to the specified direction and location.Ultrasonic sensors can used in gas, Liquid and solid. Ultrasonic has the big ability to penetrate liquid and solid.Especially in the sunshine opaque solid, it can penetrate tens meters depth.
Ultrasonic sensors are widely used in car parking assistance, proximity alarms,Medical ultrasounds, and distance measurement.

How does it work?

The Ultrasonic Sensor sends out a high-frequency sound pulse and then times how long it takes for the echo of the sound to reflect back. The sensor has 2 openings on its front. One opening transmits ultrasonic waves, (like a tiny speaker), the other receives them, (like a tiny microphone).

The speed of sound is approximately 341 meters (1100 feet) per second in air. The ultrasonic sensor uses this information along with the time difference between sending and receiving the sound pulse to determine the distance to an object. It uses the following mathematical equation:

How to calculate the time?

Time = the time between when an ultrasonic wave is transmitted and when it is received.You divide this number by 2 because the sound wave has to travel to the object and back.

Why/When to use Ultrasonic Sensors ?

1. Ideally suited to accurate, automatic distance measurement in normal and difficult environments

2. Particularly suitable for environments where optical sensors are unusable such as smoke, dust and similar.

3. Very accurate, stable and can be used over large ranges.

Ultrasonic sensors can measure the following parameters without contacting the medium to be measured:

· Distance

· Level

· Diameter

· Presence

· Position

Ultrasonic sensors make accurate measurements in many difficult environments and unusual materials. Measurements are unaffected by:

· Material

· Surface

· Light

· Dust

Mist and Vapor
