The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats or dolphins do. It offers excellent range accuracy and stable readings in an easy-to-use package. It operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect). Similar in performance to the SRF005 but with the low-price of a Sharp infrared sensor.

  • Power Supply :5V DC
  • Quiescent Current : <2mA
  • Effectual Angle: <15°
  • Ranging Distance : 2cm – 500 cm/1" - 16ft
  • Resolution : 0.3 cm

    This is great for simply DIY projects. However sometimes the readings can be off. But it is very economical so good for simple projects.
    Core electronics, once again great service as always. (Posted on 13/12/2016)

    Great little sensor works well and fairly consistently. Certainly good value for most obstacle avoidance bots. It is a pity that there is no ready made mount available. (Posted on 30/08/2016)

    Very easy to use with Arduino, good support, pretty accurate too! I'm using it to measure water level in a drinking water tank. (Posted on 10/03/2016)

    It's a well-tested unit, with plenty of python and arduino code online to modify it for your specific project... At the price, it's pretty damn awesome. (Posted on 11/09/2015)

    Many of these cost more money just for the tranducers - this is unbelievable value!

    My first delivery was crushed in the post. Probably some clod stood on the package! Graham had me a new one in no time, no quibbles whatsoever, and in packaging that may well have cost more than the item. Thanks heaps Graham, I'd have been happy if you used an old toilet roll as long as my item arrived safe! :-) (Posted on 24/05/2013)
