HC-SR04 HCSR04 to world Ultrasonic Wave Detector Ranging Module HC-SR04 HC SR04 HCSR04 Distance Sensor for arduino
Selling Point
• HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal • This module has stable performance and accurate measurement distance. • Detection distance: 0.78~196 in/ (2cm~500cm); High precision: up to 0.12 in/(0.3 cm); Detection angle: <15 °. • This module is fully Compatible with GH-311 anti-theft module. • HC-SR04 for Arduino ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back. If it back, a high level signal will be outputted by IO, and the duration of the signal is the time from sending ultrasonic to returning.
Product description
HC-SR04 Ultrasonic Sensor Power Supply :5V DC Quiescent Current : <2mA Effectual Angle: <15° Ranging Distance : 2cm - 500 cm Resolution : 0.3 cm 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.) Attention: The module should be inserted in the circuit before been powered to avoid producing high level of misoperation; if producted, power it again. The module is not suggested to connect directly to electric, if connected electric, the GND terminal should be connected the module first, otherwise, it will affect the normal work of the module. When tested objects, the range of area is not less than 0.5 square meters and the plane requests as smooth as possible, otherwise ,it will affect the results of measuring.
