In summary, the increasing demand and use of touchless interaction forces sensor companies to push the development of innovative sensor solutions because the sensors have to perform reliably in challenging environments and have to take on new tasks. Due to characteristics like weather and light independency, radar technology is ideally-suited for touchless device applications. Because of this, the radar experts at InnoSenT have developed the IMD-3000 radar system which meets the application requirements. Thanks to its functionality, it is a contactless alternative for push-buttons. The radar device detects movements in close range and triggers a technical function, such as switching on a light without touching a surface. The IMD-3000 can be used as a retrofit digital trigger for already existing devices. Additionally, it offers a compact design, easy configuration and integration, and works in challenging environments.
