The module has stable performance and accurate measurement distance. Can be compared with foreign SRF05, SRF02 and other ultrasonic ranging module. High-precision module, blind area (2cm) super-close, stable distance measurement is a strong basis for the success of this product to the market! This module is modest to the GH-311 anti-theft module

Main Parameters: 

  • Use voltage: DC5V
  • Quiescent current: less than 2mA
  • Level output: high 5V
  • Level output: bottom 0V
  • Sensing angle: no more than 15 degrees
  • Detection distance: 2cm-450cm
  • High precision: up to 0.3cm
  • Size: Length 45.34*20.37*13.70(mm)
  • Board connection mode, VCC, trig (control), echo (receive), out (empty), GND


  • The TRIP pin is an internal pull-up resistor of 10K. Use the IO port of the microcontroller to pull the TRIP pin low, then give a pulse signal of more than 10us. OUT pin is the switching output pin when this module is used as the anti-theft module. The ranging module does not use this pin!
  • The module should be inserted in the circuit board and then powered on, to avoid the occurrence of high level of malfunction, if it occurs, re-power can be resolved.

URF04 module working principle: 

  • Use IO trigger ranging to give a high level signal for at least 10us;
  • The module automatically sends eight 40khz square waves to automatically detect whether there is a signal return;
  • There is a signal return, a high level is output through the IO, and the duration of the high level is the time from the transmission of the ultrasonic wave to the return time.
  • Test distance high time * speed of sound (340M/S))/2;
  • ┬áThis product is simple to use, a control port sends a high level of more than 10US, you can wait for a high output at the receiving port. One can output the timer can be opened, when this port becomes low can be read The value of the timer, this time is the time of this distance measurement, before you can calculate the distance. Such continuous cycle measurement, you can achieve the value of your mobile measurement ~ ~
