We are on the brink of entering a world of home automation, where the various appliances in a home are equipped with IoT functionality and a range of sensors and are connected to a network, allowing them to interoperate. This new age has brought products providing services identifying, analyzing and anticipating human behavior. For example, there are devices that notice when a person approaches closer than a certain distance to a house, and start up a camera and notify the family by email.

To achieve digital transformation (DX), blending this real world with the digital world, we have developed a high-precision, miniature distance sensor using electromagnetic waves, with low energy consumption and a high cost-performance ratio. Its location detection feature, which is easy to use but has high sensing performance, dramatically broadens the possibilities of smart home IoT devices, and so contributes to creating a smart society.

Product Overview


Socionext's radio-wave ranging sensor provides value to customers with the world's top level full CMOS-based semiconductor design technology, single LSI, and package.


  • As each product has a built-in distance measurement circuit, you can use it without any knowledge of signal processing.
  • A wide range of sensing types are available, including intermittent sensing and burst sensing.
  • We offer a lineup of products with multiple reception channels that enable detection of positional information.
