All the pins are looking perfect and not bent!!! That’s great and I’ve tested the components, they work on a 230VAC!!!

Prodotto di ottima fattura.
Ne ho comprati 15 in tutto, testati uno ad uno e tutti funzionanti.
E' un ottimo componente per domotizzare le luci di casa; basta accoppiarlo con un sensore pir per il rilevamento della presenza, collegarlo alla rete wifi (ESP8266) o attraverso dei moduli a radiofrequenza (NRF24L01) e il gioco è fatto.
Nel mio caso mi creerò anche un App per poter oltre a visionare la presenza di qualcuno in varie stanze poter anche pilotare lo spegnimento o l'accensione delle luci.
Buoni acquisti a tutti :)
