Thank you for your responses.
I will only use the Raspberry Pi to send control signals to the relay. I would like to decide myself whether to apply DC or AC voltage to the COM pin of the relay.
Additionally, I want to measure temperature, read the state of a switch, and get data from a gas sensor. Do you have any suggestions for these types of sensors?
If possible, I would prefer to connect them directly to the Raspberry Pi GPIO pins. But if that’s not suitable, could you recommend a proper module?
Also, if there are any example videos or projects related to this topic, could you please share them with me?
