1pc Motion Sensor Switch Activated MP3 Sound Module With Load Output-2

Description: This product can only use 12V power supply when working with a human body sensorPIR Motion Sensor Activated Audio Player Module MP3 Sound Module with Simultaneous Load Output to Warning Light or LED Lightdescription:Features1. Equipped with a high quality audio decoder chip.2. Supports MP3 and WAV audio files.3. Built-in a 8MB flash memory, which is able to store total of about 8 minutes long MP3 files of 128Kbps.4. Equipped with a micro SD card holder, and supports max. 32GB micro SD card.5. Solder pads for connection with external USB flash drive available on the back of the board.6. Update audio files easily through the micro USB port connected with PC like using a USB drive.7. Built-in a class D 15Watts amplifier IC that is possible to drive a 10Watts 8ohms or 15Watts 8ohms speaker.8. Solder pads for audio signal out to external amplifier available on the back of the board.9. Adjustable sound volume through the blue potentiometer.10. Can be activated with a PIR sensor, micro wave sensor, switch or relay.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 45mmTechnical parameters1. Working Voltage: 9-24V DC2. Working Current: ≤2000mA3. Consumption Current at Playback: ≤500mA (12V DC)4. Standby Current : ≤15mA5. Flash memory size: 8Mbytes6. Audio format: MP3 or WAVExamples of Wiring Connections1. Connection with a PIR Sensor or a Micro Wave SensorNotes:1). The MP3 module directly supplies power to the PIR sensor. Please check the allowed power supply range for the PIR sensor before connection with the MP3 module.2). When the PIR sensor works, please make sure it outputs a signal at 3.3V or lower to the MP3 module.3). The load output ports have the 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 Switch / RelayNotes:1). A momentary switch or a relay with normally open contacts should be used. 2). The load output ports have the 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.For environmental protection, we do not provide a paper manual.
