very nice. Good item and fast delivery. I ordered it on the 19th of March and it came on the 24th of March. Will order again if I use these for any permanent projects.

Gyorsan és jó állapotban érkeztek. Teszteltem csak egyet közülük eddig, de működik, mint vártuk. Könnyen telepíthető és könnyen használható.

They arrived fast and in good condition. I tested just one of them so far but works as expected. Easy to install and easy and to use it.

The HC-SR04 sensor has 4 pins: Vcc (+ 5V), Trigger, Echo, GND. It sends a high pulse on the Trigger pin for at least 10 microseconds, at this point the sensor will send the sound ping and wait for the return of the reflected waves, the sensor will respond on the Echo pin with a high pulse of the duration corresponding to the travel of sound waves , after 38 milliseconds it is considered that no obstacle has been encountered. For safety we generally expect 50-60 millisecs to ensure that there is no interference with the next measurement.

A tárgyak időben érkeztek, nincsenek sérült modulok. Ez a tétel nem csatlakozik a tápegység, de mivel én már megrendelték, hogy a barátom, és minden rendben működik.

Items came in time,no damaged modules. This batch I have not connected to power supply but since I've been ordered it before for my friend and everything works just fine.
