Djaul88 VIP5IT14/11/2018Prodotto 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 :)Comments (0)Show Original -

0A:Yesbut for not long I have used a 120volt 8 amp motor and connected it to the relay it started heating up only after 15-30 minutes.Answered by BG223474445 on 13/01/2021Helpful (0)

0A:NoI have tried it, because you need about 70ma and at 4.2volts minimum to actually do something(I have tried with an 18650 battery). So no but you can use it with an Arduino because they can provide enough current and voltage(5v) to power 8 relays (I've tried) so your best bet is to try an Arduino and add the NodeMCU as the Wi-Fi.Answered by BG223474445 on 13/01/2021Helpful (0)

0A:Sig, vcc, gnd. You can see + and - in the picture, which would be vcc and ground! However the relay i was sent was marked with sig, vcc and gnd.Answered by schmoking on 26/02/2021Helpful (0)
