So I am working on a project and have 12v power at two separate points and I am looking to set off a buzzer using a proximity sensor. I would like to send the signal from the proximity sensor to the buzzer wirelessly. Is there a cost effective and simple way to do this? I am very new to this type of stuff.

So I bought a proximity sensor and it creates the signal when there is nothing in front of it. I need the opposite I need the signal to come when something comes in front of it. What do I need to buy?
