- The HC-SR04 Ultrasonic sensor is capable of emitting eight bursts of 40 kHz ultrasonic waves and detecting whether any pulse signals are reflected back. If a signal is detected returning, a high-level signal will be outputted through the IO pin. The duration of this high-level signal corresponds to the time taken for the ultrasonic wave to travel from the sensor, hit an object, and return to the sensor.
- The HC-SR04 Ultrasonic sensor can be used to test distance by measuring the time it takes for an emitted ultrasonic wave to reflect back from an object. The duration of the high-level signal outputted by the IO pin, when an ultrasonic wave is detected returning, is directly proportional to the distance. To calculate the distance, the duration of the high-level signal is multiplied by the velocity of sound in air (340 meters per second) and then divided by 2, accounting for the round trip of the ultrasonic wave. This formula provides an accurate measurement of the distance to the object.
- The HC-SR04 Ultrasonic sensor operates on a 5V DC power supply and has a quiescent current consumption of less than 2mA. It has an effectual angle of less than 15°, meaning it can detect objects within a narrow range in front of it. The detection distance of the sensor ranges from 2cm to 500cm, providing a wide range of measurement. Additionally, the resolution of the sensor is 0.3cm, ensuring precise and accurate distance measurements.
- The HC-SR04 Ultrasonic sensor comes equipped with an anti-reverse pin socket, which helps to make the wiring process much tighter and more convenient. This feature ensures that the connections are secure and reduces the risk of any accidental disconnections. Additionally, a 4-pin anti-reverse cable is also included with the sensor, providing an easy and reliable way to connect the sensor to your system. This cable is designed to prevent any misconnections and ensure that the sensor operates correctly and efficiently.
- The HC-SR04 Ultrasonic sensor utilizes the MCU STC15W104, which is a highly efficient and reliable microcontroller. One of the key advantages of this microcontroller is that it has a built-in clock, eliminating the need for an external crystal oscillator. This feature simplifies the design and reduces the overall cost of the sensor. Additionally, the built-in clock ensures that the sensor operates with precision and accuracy, providing reliable distance measurements.
