Help in selection of Relay shield for arduino uno


I have below component that I am going to program using arduino uno

  1. RS Water heater 200 watt AC 220/240V 50-60Hz
  2. SOBO air pump 2.5 watt AC 220/240V 50/60Hz
  3. SOBO WP-850F filter 4Watt AC 220-240V
  4. Aquarium Bulb 15 watt AC 220/240V

Please let me know which relay shield us suitable for above mention equipment to be connected to arduino uno

5 amp or 12 amp relay shield is suitable for this ?

is there any additional component require ?

appreciate your help.

Hi, A "Shield" is only one way to add components like Relays to an Arduino based system.

And it is better to NOT have 115/230V AC right close to your arduino.

Much better to use optically-isolated relays like THIS:

Lots of information available on the ArduinoInfo.Info WIKI HERE: And see THIS: about Arduino Power.

DISCLAIMER: Mentioned stuff from my own shop...

currently I have attached relay with me

which is I guess isolated relay.please see in attachment

Appreciate your help :slight_smile:
