Isi Paket
1 Module Sensor Ultrasonic Range Finder




Reliable, high performance, high accuracy, blind area within 2cm

Specification

  • Voltage:DC5V
  • Current:less 2mA
  • TTL:higher 5V
  • Sensing angle:Less than 15 degree
  • Sensing distance:2cm-450cm
  • Accuracy:about 0.3cm
  • PCB Dimension:4.5*2.0CM
  • Connection: VCC, trig(Control), echo(Receive), Out, GND


Working principle

  • Send high TTL signal at trigger IO.
  • Module automatically send 8*40khz squre wave in order to detect if there are any signal return.
  • when signal return, use each(receive) IO pin output high TTL, the output TTL time length is the time from sending till return.
  • try to use this fomula: distance = (high TTL time* velocity of sound)/2
  • velocity of sound = 340m/s
