SunFounder HC-SR04 consists of ultrasonic transmitter, receiver, and control circuit. Mode of Connection: VCC/ trig(T)/ Echo(R)/ GND (VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output.)

HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal

For Arduino Project with Ultrasonic Sensor

The HC-SR04 for arduino ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back.

When signal back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning

Operatiing Principle of Ultrasonic Sensor 

The distance can be calculated with the following formula: Distance L = 1/2 × T × C

where L is the distance, T is the time between the emission and reception, and C is the sonic speed. (The value is multiplied by 1/2 because T is the time for go-and-return distance.)

Technical Specification

Ultrasonic hc-sr04 distance measuring transducer sensor, it consists of ultrasonic transmitter, receiver, and control circuit.

HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal,When triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object.

Hc-sr04 Test Distance following formula: L = 1/2 × T × C ( L is the distance, T is the time between the emission and reception, and C is the sonic speed)

Power Supply : 5V DC; Quiescent Current : <2mA,; Effectual Angle: <15° ; Detection Distance : 2cm~450 cm; Resolution : 0.3 cm
