Radio-wave ranging sensor

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.


  • Equipped with a distance measurement circuit, it can be used without specialist signal processing knowledge
  • Can handle a variety of sensing types, including intermittent sensing and burst sensing
  • Products in our lineup have multiple receiver channels for detecting location information
