Hello Melissa Castellano,
Motion sensor can send high level signal , is it right? Is the USB cable used to power relay?
It seems you have connected montion sensor to high level signal input port. Have you tried to power on the relay and check if it can send trigger signal?
About motor connection, pleawe refer to below diagram. Relay doesn’t output power for load, it just work as switch.
You can connect independent power supply for load or relay and load share one power supply.
For any more questions, please let us know.
Best regards,
