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.
