This item will play an audio file of your choosing from the flash memory of an MP3 Player Module when it senses motion. This is an excellent gadget for holiday decorations such as Halloween or Christmas! Automate your display and play audio when a person is nearby. You could also use this in a convenience store to detect when someone has entered and play a doorbell chime. This item is also a great option for those who work in museums and want to play audio only when someone walks in front of the display or into the room. Simply plug in the 5v power supply, wait 1 minute for the PIR sensor to calibrate, and plug an AUX cable (not included) into your speaker and the device.
