The SRF05 is a new design of ultrasonic range finder and features an extended detection range. Two operational modes are available, single pin for trig/echo or 2-pin for compatibility with the SRF04.

The input trigger is a 10µS min. TTL level pulse and the echo pulse is a positive TTL level signal, with the width proportional to the object range.
  • Based around a PIC processor
  • Only requires a single 5V DC power supply
  • Typical current consumption of 30mA
  • Maximum range is a long 4m
  • New design minimises pin usage host controller
  • Ideal for low cost robotic applications

Voltage requirement5V DC
Input trigger10µs min, TTL level pulse
Echo pulsePositive TTL level signal, width proportional range

Question by Benjamin | Product code: 78-1085
02 October 2016

Q Would it be possible to connect this sensor to a PICAXE 08M (or something similar) to create a simple output that buzzes through a buzzer as the object becomes closer to the sensor? Would it be able to be programmed on the seperate PICAXE 08M via flowchart? Many Thanks
A Hi Benjamin, thank you for your question. Yes this is compatible with Picaxe, please see here for more information.
