How 24GHz Radar Sensors Change the Future of Smart Home

Intelligent sensors can measure the detailed distance of objects and can recognize and track their motion in real-time. When an object exceeds the distance threshold, the connected device obtains information from the radar and triggers an automatic alarm for the homeowner, while also sending a signal to the built-in camera to initiate video recording. This event sequence is prompted by RADAR sensing functions, as well as image recognition and data analysis functions.

According to recent market data, there are currently billions of IoT smart devices in use worldwide, and smart sensors play an important role in achieving this goal.

The 24GHz radar sensor can now be used for various connected IoT consumer devices, such as intelligent safety cameras, air quality monitors, video doorbells, intelligent lighting, video conferencing systems, dash cams, and various modern appliances and household electronic products.

Unlike traditional sensing technologies, RADAR technology has many specific advantages in locating objects, transmitting sound, and quickly transmitting data for processing.

n example - video doorbell. Nowadays, more and more homeowners and tenants are concerned about family safety, and radar sensing technology provides many advantages. For example, these sensors enable users to set physical thresholds to monitor objects or people entering and exiting important areas in front of houses. Socionext's 24GHz RF CMOS sensor can meet the needs of such applications, and is a low-power integrated device that can provide a 120 degree field of view range of up to 30 feet or more.

Intelligent sensors can measure the detailed distance of objects and can recognize and track their motion in real-time. When an object exceeds the distance threshold, the connected device obtains information from the radar and triggers an automatic alarm for the homeowner, while also sending a signal to the built-in camera to initiate video recording. This event sequence is prompted by RADAR sensing functions, as well as image recognition and data analysis functions.

By combining RADAR sensing technology with software algorithms and AI, important control and rich functionality can be provided, thus achieving many goals in smart home applications.

Ruishi Nike's SC123x series is suitable for these applications

Socionext provides a series of 24 GHz radar sensors that can detect the movement, direction, speed, angle, and position of targets.

Socionext's SC123x series integrated 24GHz radio controlled FMCW (Frequency Modulated Continuous Wave) radar sensor has a compact measurement range of 9 x 9 x 1mm and a wide detection area. They are very suitable for battery operation, with an ultra-low average power requirement of 0.5mW, suitable for human detection applications (0.1% duty cycle)

The highly integrated ultra-low power 24GHz sensor can sense entrance motion and increase distance detection without the need for external back-end processing. These characteristics make it the best alternative to PIR sensors.

When paired with an MCU, the sensor can also perform 2D angle detection.
