  • Works like a charm

    posted by Freebs

    - Works as advertized.- Very easy to work with.- Build quality is amazing.- Excellent soldering.- Great price/quality.
    For this price you can't go wrong. Top product.
    When using the standard 'Ping' program form Arduino, make sure to add a second pin to recieve the pulse. The standard program uses the same pin to send and recieve the pulse, but this product has two pins for these functions. Just add a pin for the echo, and make it recieve on this pin. After this, it'll work right out of the box.
  • Cheap, easy to use!

    Very cheapEasy to useHas a decent accuracy
    The range is about 15 cm.And for those looking to buy it for use with an Arduino, I've attached a sample code of how I used it. Obviously you'll have to calibrate it a bit first, but this will hopefully help you to get started with the ultrasone.http://pastebin.com/NzwLdUnQ
    Good ultrasone sensor for the price, only useful for distances under 15 cm! I ended up destroying mine when soldering, I accidentally heated it up too much. So I'd recommend on taking care when soldering since if the plastic inside melts it will immediately stop working, or return random values.
  • Very simple to use, good price and quality sensor

    This is a very good quality sensor, principally compared to it's complexity circuit board.It is very simple to use. If you check for some arduino codes over the web, it's just a two digital pins to keep to work.it has a fast response with good accuracy. i could measure more than 2 meters and in the other opposition 1 cm.the price is incomparable cheap due to the complexity of it's circuit board and the quantity of components necessary to it's construction.
    this is a very usefull sensor. you could use it as a proximity sensor in robots or just to check is someone is passing.it can identify non electrical os magnetical objects as plastic or water in a bottle, this is very usefull too.I used it a very simple and powerfull library from: http://www.f15ijp.com/2012/09/arduino-ultrasonic-sensor-hc-sr04-or-hy-srf05/
    Buy this sensor. You can inprove your projects and build some other very nice and usefull stuffs with it's help.It's cheap and easy to use.besides the miss of documentation, with some minutes on the web you can have it all you need about it.
  • Pretty simple to use

    The overall quality of this product is really good, so the price is really cheap, it works just fine with my diy arduino clone. Works just fine with the arduino code which is available on the web
    The packing again, it could be improved, also it took me a bit longer than 15 days to get the item delivered, it was worth the wait though.
    It is a good product for your hobby robotics projects or any distance detection project. The money payed for it was worth it
  • nice product

    it is nice to work for estimated mesurement.it is very easy to use.it is very light to hold it.the display is easy to read.the shape is line traditional meter, and it is nice.the battery is standatd and small, can be used for a long time.
    for the price it is a nice measurment device.in a second thought, a laser distance meter it is better for more accurate usage.
    nice device.
