1). Can be driven from a 5V power supply like a phone charger with USB socket and the same USB connector used to update files to the internal flash memory or Micro SD Card via computer.
2). Support to store audio files either on internal flash memory or a micro SD card.
1). Adopts a PIR motion sensor that can detect max. 4 meters. When it detects a moving human body, the module automatically plays a sound in random among the multiple sounds stored in the flash memory.
2). Built-in a 8MBytes(64Mbits) SPI flash memory and supports max. 32GB micro SD card as well(normally the on-board flash memory is large enough).
3). Update audio files to the flash memory directly via the micro USB port connecting with computer. The on-board flash memory works as a USB flash drive on computer.
4). Equipped with a good quality speaker hidden in box. The sound volume is adjustable through the blue potentiometer.
5). Equipped with a 3.5mm audio jack for stereo output that can drive a headphone directly or connect with an external amplifier.
6). 3.7V-5V DC power input. Also possible to use a 5V 1A power adapter or power bank to supply power to the module via the micro USB socket.
7). PCB size: 40mmx40mm
8). Diamter of the speaker box: 58mm
Height of the speaker box: 28mm
1). Working voltage: 3.7-5V DC
2). Working current: ≤200mA
3). Power Consumption: ≤3W
4). On-board flash memory size: 8MBytes(64Mbits)
5). Audio format: MP3 or WAV
6). Distance of PIR detection: 0-4 meters
7). Detection angle: 120 degrees
Note: The PIR sensor has about 15 seconds initialization time whenever the module is powered on. During this, it's normal the PIR doesn't work. And once the initialization is done, it will be into working condition immediately.
