DT-SENSE UltraSonic Ranger (USR)

DT-SENSE Ultrasonic Ranger (USR) is a distance measuring module is non-contact so easily connected with a variety of microcontroller-based systems. The process triggers (trigger) and read the measurement data with the DT-SENSE Ultrasonic Ranger only need 1 piece pin microcontroller. Examples of the use of DT-SENSE Ultrasonic Ranger is for intelligent robot, smart vehicle, automatic doors, security systems, distance measuring objects, and so forth.


  • Distance range: 2 cm to 3 m.
  • Burst Frequency: 40 kHz - 16 Vpp signal box.
  • No dead zone (no blank spots between 2 cm to 3 m.
  • Having interface Pulse Width / Pulse Width.
  • Rapid measurement cycle.
  • Readings can be done every 25 ms (40 Hz rate).
  • Trigger Input: TTL negative pulse, 20 us (at least).
  • There are LED indicators that show activity sensor.
  • Requires no delay before the next measurement.
  • There is an example program using C language for microcontroller AVR AT90S2313 and language BASIC for the MCS-51 microcontroller.
  • Requires 5 VDC voltage source.
  • Current consumption of around 17 mA (typical).
  • Dimensions: 5.5 cm  x 3 cm  x 2 cm
