Voice Playback Module with inbuilt amplifier [ LVDA-V2 ]
This amplified voice playback module is ideal for any situation were a voice recording is needed for alerting somebody. It enables you to store a personalized recorded message, and playback this message back once a sensor / input attached to this voice module is triggered.
Most common alerting devices sound a high pitched buzzer. For the elderly / visually impaired, this can become annoying, but more importantly does not warn them of any dangerous situation. A sounded message like "don't touch", "hot water" ... etc is much more useful.
All you need is to simply connect power, a speaker, and any external sensor / trigger device.
