SleepSense Snoring Sensors respond to snoring and other sounds in the audio range picked up through the skin, and convert them to a small analog voltage that provides a clear, reliable indication of the presence of these sounds. SleepSense Piezo Snore Sensors are designed with a large sensitive area to improve signal stability and a soft, flat surface to seal against ambient noises. This sensor was designed for use with Alice 6 Systems.
