Ever wanted to use low cost ultrasonic distance sensor on 3.3V system such as Espresso Lite V2.0 or NodeMCU? HC-SR04 can only be powered at 5.0V, this constrain the usage on 5V system.

Now this tiny ultrasonic distance/range sensor can work from 3.0V to 5.5VDC, and the interface protocol is compatible with HC-SR04, you can utilze the sample code of HC-SR04 :) Best of all, it specially designed IC that minimize the blind range to 1cm from sensor (HC-SR04 is 2cm).

Ultrasonic sensor is created based on the principle of echolocation used by animals like bats and dolphins. Since ultrasonic sensor uses sonar to determine the distance to an object, its operation is not affected by sunlight, spotlight and object's surface color which will affect the readings of any infrared distance sensors. However acoustically soft materials such as clothes can be difficult to detect.

And of course it is compatible with Arduino :)

Features/Spec:

  • Working Voltage: 3.0V to 5.5VDC
  • Compatible with HC-SR04 protocol
  • Pin to pin compatible with HC-SR04, direct replacement
  • Minimum detection distance: 1cm
  • Maximum detection range:
    • 3.3V: 400cm
    • 5.0V: 450cm
  • Operating current:
    • 3.3V: 2.2mA
    • 5.0V: 2.8mA
  • Resolution: 1mm
  • Detection angle: 15º
  • Operating temperature: -20ºC to +80ºC

Do you maybe have the datasheet of this sensor? ( Marieke Schippers, 19/03/2020 )
Hi, we're sorry as we do not have it for now. Thanks :)
Im use HC-SR04 before. So if I change to this sensor, the Arduino coding will work right? ( Taufiq, 08/04/2019 )
Hi, yes it will work since the connection pin is same, but you still need to do some calibration on the distance. 
So this ultrasonic sensor can detect changes up to 1mm difference?
( ZHEN HUI KOK, 24/03/2019 )
Hi, yes the smallest change that this sensor can measure is 1mm.
