Hc Sr04 Ultrasonic Sensor Is Arduino Ultrasonic Distance Measurement Sensor Its Application Could Be As Liquid Level Sensor Tank Le Arduino Ultrasonic Sensor from www.pinterest.com
As shown above the hc sr04 ultrasonic us sensor is a 4 pin module whose pin names are vcc trigger echo and ground respectively. The us sensor can be powered by 5v and hence it is directly powered by the 7805 voltage regulator. As shown above the hc sr04 ultrasonic us sensor is a 4 pin module whose pin names are vcc trigger echo and ground respectively.
As shown the circuit involves nothing more than a lcd display and the ultrasonic sensor itself.
This sensor is a very popular sensor used in many applications where measuring distance or sensing objects are required. Ultrasonic sensors exhibit excellence in suppressing background interference. The ultrasonic sensor has four terminals 5v trigger echo and gnd connected as follows connect the 5v pin to 5v on your arduino board. These transducers are better than the infrared sensors because these ultrasonic transducer sensors are not affected by the smoke black materials etc.
