What handles 220 V AC in Arduino?
What handles 220 V AC in Arduino?
Arduino में 220 V AC को कौन handle करता है?
A.
Bluetooth module ब्लूटूथ मॉड्यूल
B.
Relay module रिले मॉड्यूल
C.
DHT sensor / DHT सेंसर
D.
LDR
Correct Answer is :
B. Relay module
Explanation
An Arduino should not directly switch a 220 V AC load. A suitably rated relay module can allow a low-voltage Arduino control signal to switch an isolated high-voltage load.
Arduino से 220 V AC load को सीधे control नहीं करना चाहिए। उचित rating वाला relay module Arduino के low-voltage control signal की सहायता से high-voltage load को electrically isolated तरीके से switch कर सकता है।
