Digital Display for HC-SR04 Ultrasonic Distance Measurement Control Board adopts 8 bit MCU as the main control chip; it can be applied in distance measurement, testing HC-SR04 ultrasonic module performance. And it supports serial port display and digital tube display.

Features :

  1. Onboard STM8S103 high-performance microprocessor.
  2. With digital tube display.
  3. Serial port data output.
  4. Valid Measurement Distance: 3-400cm.
  5. Display Unit: cm.
  6. Max Error: 5V.
  7. Board Size: 36 x 25 x 12 mm.
  8. VCC, GND: 5V power interface.
  9. 2.54mm White Socket: 5V power interface.
  10. TX: module serial port transmits pin.
  11. RX: module serial port receive pin.
  12. NRST, SWIN: preset STM8 program download port.

Using Introduction:

1. The measurement distance can be displayed via a digital tube and serial port.
Digital Tube Display: directly plug in the ultrasonic module, connect 5V power.
2. Serial Port: plug-in ultrasonic module, VCC, TX, RX, GND respectively connects 5V, RX, TX, GND of USB to TTL module; serial port communication baud rate 9600, output format “D:XXXrn”; XXX represents distance, unit is cm.


1. When measuring the distance, the area of a measured object should be no less than 0.5 square meters, and it should be smooth and has strong reflectivity; otherwise, it will affect the test result.
2. Valid Measurement Distance: 3-400cm; if longer than this range, it will lead to incorrect data or 000 display.
