  • Ultrasonic measure

    posted by ecqu000

    This device is surprisingly accurate. You can constantly measure, update speed is quite good.You can easily calculate area/volume, also you can add, subtract and store measurements. Auto turn-off, same for laser pointer it has.0,5 - 10m measurements easily and quickly done.Build quality is acceptable, nothing too fancy but nothing bad about it either, it's rather good.
    It shows temperature when you switch it on.Laser pointer is hardly visible in daylight past 10m.Anything in the path of ultrasonic waves will reflect and cause error in reading. Very lightweight. Need to use laser to make sure you hold it at right angle, and avoid error readings.
    It could have more range, but that's where you need more expensive laser measure. In ranges up to 10m works exceptionally well, higher than that you need to be a bit more careful. If this devices capabilities meet your requirements you can safely get one.
  • Great for close range applications

    Cheap, reliable, easy to use with Arduino NewPing library. Good precision around 0.5 cm on 30 cm range and 2 cm on 100 cm range.
    Datasheet Specifications:power supply :5V DCquiescent current : 2mAeffectual angle: 15ranging distance : 2cm – 500 cm this is really more like 200cmresolution : 0.3 cm
    Great for close application 2 - 200 cmI already have a SR04 and plan to use these two for obstacle avoidance. They have a quite wide beam so they are not that good for mapping.
  • 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.

    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.
