Hi,
i need some help regarding a project that i am doing now. i nid to know how do i go about connecting an 230VAC fan to a dc sensor. the dc sensor will control the power and oscillatory of the fan. is the method from the power supply socket, its connected to the dc sensor, then the output goes to the fan? if i am wrong, i need some guidance. thanks

I dont know what is your sensor!
But you can use DC power supply for driving sensor, and connect
sensor to one relay.
Now N.O. contacts of relay can be used to switch AC fan.

If you introduce your sensor i can guid you better.

the solid state relay is not an electromechanical device it is electronic relay may be of thyristor or triac or else. so there is no spark in the electronic relay during contact or release
