Using a Piezo-electric crystal, the SleepSense Piezo Snore Sensor (# 1250) with safety DIN connectors converts vibrations in the neck caused by snoring to a small analog voltage that provides a clear, reliable indication of the presence of snoring. SleepSense implemented a small bump into the design of the Piezo Snore Sensor, which maintains constant contact with the patient's skin throughout movements or sweating, ensuring consistent quality signals throughout the night with little to no artifact. Warranty: Factory 6 Months - Free of Defects in Materials and Quality Workmanship. NOTE: SleepSense items are for professional use only, and are for sale by or on the order of a physician only. This device is for diagnostic purposes only and not for use as an apnea monitor. SleepSense Piezo Snore Sensor Features & Specifications: Immune to ambient noise.
