Pros:
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. Выводы. — Получившийся датчик присутствия мне понравился. — Простейшая и удобная настройка. — Реально работает. — Дешево и сердито.
Cons:
Нет

Pros:
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.
Cons:
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.

Pros:
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.
Cons:
None.

Main Features:
● Static Current: Less than 2mA
● Output Signal: Electric frequency signal, high level 5V, low level 0V
● Sensor Angle: Not more than 15 degrees
● Detection Distance: 2cm-450cm
● High Precision: Up to 0.3cm
● Input Trigger Signal: 10us TTL impulse
● Echo Signal: Output TTL PWL signal

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

Pros:
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
Cons:
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)

Pros:
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.
Cons:
None.

Pros:
this sensor is foрfixing distance, also you kan use for some arduino projects or other things.I post some photos of this and in that photos you can see the size of thi product and other things.If you have question you can ask me 24/7.

Pros:
Non ha particolari difetti, se non il suo non esser giustamente troppo precisio sulle piccole distanze. si usa tranquillamente con l'IDe di arduino e online è facile trovare guide che spiegano come usarlo. Non ho incontrato paeticolari difficoltà di utilizzo e quindi non ho trovato particolari difetti a qeusto prodotto che semrba esser davvero ottimo.
