Packed in a 64-pin BGA package measuring 9- x 9- x 1.18-mm, the low-cost SC1230 Series includes two products that can detect the location and movement of individuals with ultra-high degrees of sensitivity. The SC1232AR3 measures the presence and the distance of an object, while the SC1233AR3 adds the ability to detect direction. The two sensor options provide total flexibility for customers worldwide. Both are available now in samples, with volume production scheduled for the first quarter of 2020.
Incorporating basic signal processing functions into the sensor device reduces the number of external components, and makes it easier to use without specialized knowledge in signal processing. With a built-in antenna, the chips operate at 0.5 mW for detection of persons operating at a 0.1% duty cycle in motion detection mode, with a supply of 1.8- to 3.3-V. As they don’t record images or sounds, the sensors are useful for developing new services and functions based on information about “human behaviour,” while also addressing privacy concerns.
Additionally, the radar sensors can operate behind non-metallic surfaces, walls or plastic housing to generate behavioural data such as movement, direction and distance. In comparison with conventional radar sensors, the SC1230 require no advanced knowledge to implement. They are also smaller, far less power-hungry and easier to install in home appliances.
