Motion Sensor Activated MP3 Player Module Button Triggered Sound Module with 15W Class D Amplifier

Features

1. Equipped with a high quality audio decoder chip.

2. Supports MP3 and WAV audio files.

3. Possible to be activated with a PIR motion sensor, a photoelectric sensor, a button switch or a relay. 

4. Built-in a 8MB flash memory, which is able to store total of about 8 minutes long MP3 files of 128Kbps. 

5. Equipped with a micro SD card holder, and supports max. 32GB micro SD card. 

6. Solder pads for connection with external USB flash drive available on the back of the board. 

7. Update audio files easily through the micro USB port connected to PC like using a USB flash drive.

8. Built-in a class D 15Watts amplifier IC that is possible to drive a 10Watts 8ohms or 15Watts 8ohms speaker.

9. Equipped with a 3.5mm audio output jack that can drive an earphone directly or connect to an external amplifier.

10. Adjustable sound volume through the blue potentiometer.

11. Optional to play a sound in order or in random after each activation when there are multiple files in the memory.

12. When a sound is playing, there is a load output simultaneously, which can directly drive a warning light, LED light or LED strip. 

13. A busy output available as well. It outputs high level when playing and low level when standby.

14. Great sound quality and stable performance.

15. PCB size: 45mm x 45mm

Technical Parameters

2. Working Current: ≥2000mA

3. Standby Current : ≤10mA

4. Flash memory size: 8Mbytes

5. Audio format: MP3 or WAV

Examples of Wiring Connections

1. Connection with a PIR Motion Sensor

Note:

The load output ports have the exactly same voltage as the power supply you use, so if you need to connect with a 12V light, the power supply you need to use must be 12V. If you don’t need to connect with a light, just ignore this. 

2. Connection with a Button or Switch 

Note:

The load output ports have the exactly same voltage as the power supply you use, so if you need to connect with a 12V light, the power supply you need to use must be 12V. If you don’t need to connect with a light, just ignore this.
