In todays digital world we are using many types of sensors in our daily life. our watch, mobile, home gadgets every thing is operated with Sensors, the most important sensor is Ultrasonic sensor. An ultrasonic sensor is an electronic device that measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical signal. In this video we are explaining complete working, Application as well as interfacing of ultrasonic HC-SR04
Ultrasonic technology में sound waves को send और receive करके दूरी नापी जाती है. आप सोच रहे होंगे की sound waves है तो हमे यह सुनाई क्यों नहीं देती? यह waves high frequency range की होती है इसलिए हमे सुनाई नहीं देती है. हम मनुष्य 20 Hz से 20 kHz तक की frequency सुन सकते है और ultrasonic 100 kHz से 50 MHz पे काम करता है. एक Regular interval पर pulse send करते है और कोई object से टकराकर यह pulses reflect होती है जो receiver receive करता है. send और receive करने के लिए अलग transducer होता है. Send pulse और Receive pulse के बीच का time नाप के दूरी नापी जाती है.
An optical sensor has a transmitter and receiver, whereas an ultrasonic sensor uses a single ultrasonic element for both emission and reception. In a reflective model ultrasonic sensor, a single oscillator emits and receives ultrasonic waves alternately. This enables miniaturization of the sensor head.
So in this video we have explain how this sensor will work, how we can use it for our project or in our daily life. this video is divided in two parts. 1. Theory and 2. will be the practical use of this sensor. the second video will uploaded soon.
