SunFounder Ultrasonic Module HC-SR04 Distance Sensor Compatible with Arduino R3 Mega2560 Duemilanove Nano Robot Rapsberry Pi 4B 3B+, 3B, 2 Model B & 1 Model B+
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 Compatible with Arduino Project with Ultrasonic Sensor The HC-SR04 compatible witharduino 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 Read more 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 Read more Package List 5 HC-SR04 Ultrasonic Sensors , 10 Female-Male Dupont Cables , 10 Female-Female Dupont Cables , 1 Exquisite package box Read more
