This product is a sleep monitor device designed exclusively for elderly hospital patients. Its infrared sensor detects their motion in bed, so that if a person accidentally falls out of bed or has been immobile for too long, the embedded sensor will send an alarm message to the hospital staff, who can then respond quickly with treatment or first aid. In addition, the product is also able to monitor body temperature, ambient temperature, and humidity, and controls air conditions to create a comfortable sleeping environment for the elderly.
