The FX12 is an analog amplifier: it will amplify small signals from piezo and other low level sensors for reading by a 0-10V input. Commonly used for knock-knock, microphone, and other puzzles where a sequence of analog pulses is detected to trigger an action.
This product is just the analog amplifier. You will also need a BAC V with any FX45 expander module (not included).
Instead of this product, we typically recommend purchasing our FX12-KNOCK kit with a pre-wired knock-knock sensor instead.
Simply connect, configure, and knock another puzzle off your to-do list!
