Radio-wave ranging sensor

Precision to realize smarter world

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 highprecision, miniature distance sensor using electromagnetic waves, with low energy consumption and a high costperformance 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.
