Sensors monitor breathing through walls

Norwegian sensor specialist Novelda has launched two sensor modules for detecting human presence and monitoring respiration.

The sensors are based on its proprietary XeThru technology, which uses RF technology, rather than infrared, ultrasound or light. This approach allows the modules to 'see through' objects, including lightweight building materials, duvets and blankets, to provide non-contact sensing at distances of up to 4.8m.

The X2M300 sensor is intended for smart home automation where its capability for detecting human presence while being integrated into a building's structure enables hidden, tamper-proof sensing. This could be used for home comfort and security applications.

The X2M200 sensor is designed for respiration monitoring for health and welfare purposes. It has a range of 0.5m to 2.8m and can be placed on a night stand, wall mounted or fitted into the ceiling above a bed.It is suited for sleep improvement systems and detecting sleep anomalies or other medical conditions.

Modules consume less than 400mW and are said to be unaffected by dust, smoke, moisture or darkness.
