Applications of Radar Technology in Smart Homes

Intuitive sensing applications drive this market growth, which allows humans to engage with smart gadgets more naturally and seamlessly.

FREMONT, CA: One of the fastest-growing segments of the IoT market is smart homes. It is also the segment in which radar technology functions as a catalyst to improve applications' functionality, precision, energy consumption, and cost. In particular, the rising availability of low-cost, low-power radar sensors enables a new generation of smart home applications that range from greater security and safety to enhanced convenience and comfort. Millions of sensors and gadgets connect the planet, as IoT gadgets improve life and save money. Smart device and application demand is rising as consumers seek comfort, energy efficiency, and security from smart technologies. Intuitive sensing uses non-intrusive sensing technology to give IoT applications new perceptions.

Automatic door control: Radar sensors for intuitive sensing offer information on motion and approaching and leaving motions. It enables applications for automatic door control in which doors open only when a target is continuously coming and not when other types of action are recognized. The radar is usually installed on a wall or ceiling and emits modulated signals continually.

Presence or absence detection: When equipped with radar sensors, intelligent devices can detect the presence or movement of humans, enabling a vast array of optimization applications. For instance, when no one is present, a radar-based smart gadget can automatically enter sleep mode and conserve energy. For example, radar sensors enable chair exit systems that assess if a person has left their seat and has not returned within a predetermined time.

Segmentation and tracking: Radar sensors can offer numerous intelligent features to devices like sound systems. Sound systems could track the listener's location and continuously adjust volume and suitable parameters accordingly. Radar technology permits the creation of cutting-edge solutions for senior care. For example, they enable bed-exit devices that detect if a person has left their bed and has not returned within a few minutes.

Heating control systems: Radars enable underfloor heating system controls that detect the presence of a person and activate or deactivate the heating system accordingly. They can track the distance and location of a person within a room to modify the fan speed and direction of the air conditioner's blades. These use cases enhance the comfort of inhabitants while enhancing environmental performance and sustainability.

Vital signs monitoring: Similar radar systems can monitor heart rates and breathing patterns. The information can get utilized over time to detect abnormalities in the heartbeat pattern, which may suggest cardiac arrhythmia or other issues. Detection of heartbeat patterns provides many creative lifesaving applications in infant and senior care. Most of these features can get collected at a distance based on body movement, even in dim illumination.
