Ultrasonic Wave Detector Ranging Module PICAXE Microcontroller Sensor HC-SR0 for Arduino/51/STM32

the module URF04 works:

  • (1) IO trigger ranging to at least 10us high signal;
  • (2) module automatically sends eight 40kHz square wave, automatically detect whether a signal return;
  • (3) a signal to return to a high IO output, high duration of the ultrasonic time from launch to return.
  • Test distance = (time high * speed of sound (340M / S)) / 2;

main technical parameters:

  • 1: Voltage: DC5V
  • 2: Quiescent Current: <2mA
  • 3: level output: the output of the high-5V
  • 4: level: the end of 0V
  • 5: Induction Angle: not more than 15 degrees: detection range: 2cm-450cm
