  • 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.
  • Incredibly well priced

    This module is surprisingly sensitive (you'll need to calibrate it, but it works well afterward) for its price and has a much smaller minimum sensing distance than most sensors I've seen in the <$30USD range.
    You'll probably need a crystal or other high precision oscillator to be able to use this for anything beyond collision detection. I wouldn't use it for laboratory equipment, but it's definitely suitable for near by object detection or amateur robotics.
    Like any ultrasonic range sensor, it has its limitations, but it is by a wide margin the cheapest module of this quality level. I'd highly recommend it for hobby or educational use.
  • 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.
