Tinydeal non delude neanche stavolta. Ho comprato più di un prodotto per Arduino e sono tutti perfettamente funzionanti, l'imballaggio li ha ben protetti nel lungo viaggio. Il sensore funziona bene, sono presenti quattro pin, due di questi dedicati all'alimentazione, mentre gli altri due all'emissione dell'impulso di trigger e alla ricezione del suo ritorno (echo). Sono facilmente reperibili online numerose guide su come utilizzarlo

Il sensore funziona benissimo e non ho avuto alcun problema ad usarlo con la mia scheda arduino. La distanza viene rilevata in maniera abbastanza precisa. Provato fino a 7 metri circa ha dato dei risultati soddisfacenti.

Заказал. Товар пришел за 2 недели. Доволен. Цена достаточно низкая по сравнению с нашими в городе. Думаю сделать что то наподобие электронной рулетки на данном датчике. Спасибо магазину.
