Frequently Asked Questions:
Q1. Why are these called "Arduino Compatible"?
A1. The Arduino group demanded us to remove their logos and rename these products so that they do not lead customers to believe they are the same units sold by Arduino
Q2. Are these 100% compatible with the "normal" Arduino's?
A2. Yes, they really are completely compatible with "normal" Arduino's. Build quality looks the same and everything (studio, library, tools, etc) just works

    Датчик растояния
    Максимальные 4 метра подтвердить не удалось. Максимальное расстояние которое удалось подтвердить, где устройство уверенно фиксирует человека равно 3.5 метра. На з-х метрах уверенно фиксирует мою руку с коробкой 15х15 сантиметров. Включает нагрузку и не отключает, пока коробку не уберешь.
    — Получившийся датчик присутствия мне понравился.
    — Простейшая и удобная настройка.
    — Реально работает.
    — Дешево и сердито.

    I may just be lucky
    I received what I ordered and it functions out of the box. I have yet to put it through its paces for accuracy testing for now it works and I am happy with it. The free shipping was a plus, though I imagine at this price level they lost money getting this sensor to me as I purchased only one as a tester of their service. In the future I will buy more in bulk.

    Works great with an MSP430 launchpad.
    I am spoiled for the speed at which services such as amazon or newegg ships out items. This took over a week to leave their warehouse and it took awhile to get here, though they ship out from China so I can't blame them. The build quality of the board is functional, however there is some proximity issues on some of the solder points where bridging could occur if you got an unlucky part.

    Not a toy, but a good module
    This module should be relisted as something other than a toy (it has to be rated as a toy in the review process). Regardless of that, I bought this module instead of the Ping sensor, mostly because this one was less expensive and cost was an issue for this project. It easily integrated with an Arduino and I quickly coded it up to convert the output to distance. It works quite well so far.

    HC-SR04 Arduino Ultrasonic Distance Measuring
    Very accurate calculation of the distance
    Long distance read
    Can make many reads per second (more than 50Hz surely)
    It seems to be good quality product
    Small size allow to use it whenever you want
    Helped a lot my RC project
    I used it as an emergancy braking system, which is working really well
    If this can count as a con is that it is not totally silence
    You can hear it sending the sounding waves (sound is equal to the readings - the more the readings per second the more frequent the sound is)

    NOT a toy
    I bought this for my son who is an honors student in the Electrical Engineering program at a university.

    This is no toy.

    He is using it with a program he is writing for his arduino.

    Why they call this a toy is astounding.

    This is a fairly sophisticated electrical component that you program.
