Introducing our innovative Audio Player with PIR Motion Sensor, designed for seamless integration and the automatic triggering of audio alerts by motion detection. Explore the standout features of this versatile device:
Flexible Motion Sensing:
- Features a separate PIR motion sensor, allowing for flexible and convenient placement separate from the audio player.
Customizable Options:
- Available in two models: one with a single PIR sensor and another with dual PIR sensors, giving users options tailored to their specific needs.
Independent Sound Triggering:
- In models with dual PIR sensors, each sensor can independently activate its associated sound file, allowing for simultaneous playback without interruption.
High-Quality Audio Playback:
- Equipped with a high-quality built-in MP3 player and 8MB of flash memory, ensuring reliable and immersive audio playback.
Extended Storage Options:
- Supports USB flash drives and microSD cards as additional storage options, with a capacity of up to 32GB each.
Powerful Amplification:
- Comes with a class D 10-watt amplifier for loud and clear audio output.
User-Friendly Operations:
- Allows easy uploading of audio files via a micro USB port connected to a computer using a USB data cable.
Adjustable Volume:
- Features an integrated potentiometer for easy volume adjustment.
Versatile Connectivity:
- Capable of driving external equipment, such as warning lights or motors, while simultaneously playing audio.
Audio Output Flexibility:
- Includes a 3.5mm audio output jack for connections to external amplifiers or active speakers.
Durable Construction:
- Encased in a robust aluminum alloy case to ensure durability and longevity.
Industrial-Grade Design:
- Boasts an industrial-grade build that provides strong anti-jamming capabilities.

This device has seven trigger input terminals labeled K1 through K7. However, we only use the first two terminals (K1 and K2) to connect external PIR sensors. The remaining terminals (K3 to K7), as well as the 485+ and 485- terminals, are designed for other purposes and should not be altered or used.
-
When a sound is playing, you can simultaneously activate an external LED light. The output voltage at the "Load+" and "Load-" terminals for the LED light matches the device's power supply voltage. For example, if the device is powered with 12V, the LED light must also support a working voltage of 12V.

Note: There is a config file "Config.txt" on the internal flash memory. Please don't delete it when you update audio files.
Power adapter NOT included. We suggest you use a 12V 2A power adapter.
Jargon buster
Plain-language definitions for the technical terms used above.
- Flash memory
- Non-volatile memory that keeps stored data even when power is removed. In this sensor, it matters because enrolled fingerprint templates can remain saved after the project is turned off.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- Motion detection
- A camera feature that checks the image for changes that suggest something has moved. It matters because your project can use movement as a trigger instead of constantly saving or processing every frame.
- PIR sensor
- A passive infrared sensor detects changes in heat, usually from a person moving across its view. It matters because PIR sensors are common for lights and alarms, but they can miss people who are present but not moving much.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
