NOTIFY ME WHEN IN STOCK

HC SR04 HC-SR04 Ultrasonic Sensor also called HC-SR04 Ultrasonic Range Finder. Ultrasonic Sensor module HC-SR04 provides 2cm – 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules include ultrasonic transmitters, receiver and control circuit.

The ultrasonic sensor uses sonar to determine the distance to an object like bats or dolphins do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. From 2cm to 400 cm or 1” to 13 feet. Its operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect). It comes complete with the Ultrasonic Sensor transmitter and a receiver module. This is easily interfaceable for many microcontrollers like Arduino uno r3, Microchip PIC and ST Microcontrollers.

HC-SR04 HC SR04 Arduino Ultrasonic Sensor

What is Ultrasonic?

Ultrasound is high-pitched sound waves with frequencies higher than the audible limit of human hearing.

HC-SR04 HC SR04 Arduino Ultrasonic SensorHuman ears can hear sound waves that vibrate in the range from about 20 times a second (a deep rumbling noise) to about 20,000 times a second (a high-pitched whistling). However, ultrasound has a frequency of over 20,000 Hz and is therefore inaudible to humans.

 

Basic working principle of ultrasonic sensor

  1. IO trigger for at 10µs high-level signal
  2. The Module automatically sends eight cycles of ultrasonic burst at 40 kHz and detects whether there is a pulse signal back.
  3. If the signal is reflected back, through a high level, time of high output IO duration is
    the time from sending ultrasonic to returning.
Distance =  [high-level time × velocity of sound (340M ⁄ s)] ⁄ 2

 

Sensor Differences
 

Alright, let’s get straight into the topic and see what are the difference between the two newer and older versions of HC-SR04-P ultrasonic sensors. Well, to be frank, both of them actually provide an approximately similar outcome in terms of distance measuring same goes for the working principle which consists of 1 transmitter and 1 receiver.

To clarify this is NOT the same as the HC-SR04 since the name of the ultrasonic sensor is very similar and it operates at 5V only. The ones we will be looking at and comparing is the 2021 and 2022 version of HC-SR04-P ultrasonic sensors, both operate at the voltage 3V – 5V.
