In Stock


The Ultrasonic Ranging Module provides stable readings and accurately measures distance. This module can be used for a number of projects such as fluid level in a tank, distance to obstacles, and other sensing tasks.


  • Working voltage : 5V(DC)
  • Static current: Less than 2mA.
  • Output signal: Electric frequency signal, high level 5V, low level 0V.
  • Sensor angle: Not more than 15 degrees.
  • Detection distance: 2cm~450cm.
  • High precision: Up to 3mm
  • Mode of connection: VCC / trig(T) / echo(R) / GND



  • Initiate IO trigger by supplying at least 10us high signal
  • The module automatically sends eight 40khz square waves and detects the returning pulse signal if available
  • Unlike in the photos, a 25 cent coin is not included



Warranty is valid for two weeks, starting upon date of receipt.
