HC-SR04 Ultrasonic Sensor

Category: SKU: uss
  • Its power supply value is 5V DC.
  • Its quiescent current value is <2mA.
  • Its working current value is 15mA.
  • Its Effectual Angle is <15 degrees.
  • Its distance range is 2cm – 400 cmm.
  • 20mm – 5000mm Ultrasonic sensing distance
  • 3mm positional accuracy.
  • 5V Supply Input
  • All processing done onboard and a single output pin returns a pulse-width proportional to object distance.
  • Works by sending a 40kHz pulse and measuring the time for the pulse to be ‘reflected’ by an object, then using the speed of sound(~340m/s in air) the distance can be calculated.
