Page 2 1. Introduction MOD611 is 60GHz mmWave IoT radar sensor for a more intelligent and safer monitoring system. Reliably detecting presence, movement and breathing without the use of intrusive cameras or wearables. It can detect a person even if there is no movement or is under blanket as it detects vital signs like breathing or micro vessel flow. In addition, abnormal signs such as apnea can be detected and alerted in real-time to prevent sudden death of infants or to monitor the elderly person who are living alone, a person with dementia, or hospitalized patients. There is no blind spot within the sensing area and are not affected by obstacles such as blankets or clothes. It can be used in dark and humid environment and does not invade privacy because it does not acquire optic information. There is no need to wear wearable devices and is easy to install. 2.

Sensor Operation 3.1 Presence and Breathing Detection 3.1.1 Detect Condition Target person must be within 0.2m to 3m detection range. If more than one person is present in the detection zone, the MOD611 sensor will measure the one whos movement is bigger. Metallic objects should be avoided. 3.1.2 Sensor Detection Result Absence: When there is no person present Presence: When there is a person present (Person is still and breathing normally) Motion: When there is a person present and movements are detected Apnea (No Breathing): When there is a person present, but no breathing has been detected for certain time*

(* Apnea is defined when there is no breathing for 10 seconds for Adults and 20 seconds for Baby) 3.1.3 Adult Bed Installation Guide Copyright 2020 bitsensing All Rights Reserved.
