Πολύ ωραίο, καλό αντικείμενο και γρήγορη παράδοση. Το παρήγγειλα στις 19 Μαρτίου και ήρθε στις 24 Μαρτίου. Θα παραγγείλω ξανά αν τα χρησιμοποιήσω για μόνιμα έργα.

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.

Parecem muito bons na qualidade, não testei ainda, o melhor que recebi em 20 dias em Rondônia, Bangoog é a melhor na qualidade de entrega....

Έφτασαν γρήγορα και σε καλή κατάσταση. Δοκίμασα μόνο ένα από αυτά μέχρι τώρα, αλλά λειτουργεί όπως αναμενόταν. Εύκολα εγκαθίσταται και εύκολα και χρησιμοποιείται.

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.

Τα αντικείμενα ήρθαν στην ώρα τους, δεν έχουν υποστεί ζημιές. Αυτή την παρτίδα δεν την έχω συνδέσει με την παροχή ρεύματος αλλά από τότε που την παρήγγειλα πριν για τον φίλο μου και όλα δουλεύουν μια χαρά.

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.
