Sense and Sound Audio Recordable Motion Sensor
Raise attention and create impact by adding sound to your displays or role play areas with this recordable motion sensor.
Record your own 10 second voice message or sound effects which are then activated by movement.
Other features include:
• 2m range
• High quality sound playback
• Adjustable volume control
• Built-in microphone
• Audio jack for recording from a CD player, MP3 player or computer.
Seems rather unpredictable as to when it detects motion. Light levels seem to be critical to consistent operation and it would probably work OK in a classroom or exhibition area (not so good in domestic environment, as I am finding).
