The devices uses impulse radar to reliability detect human presence detection and save energy in automation and consumer electronics

NOVELDA AS, a developer of accurate and reliable human presence sensors has launched its latest Ultra-Wideband (UWB) sensors for smart home and building automation that can accurately sense human presence and motion providing for accurate touch-free interaction with everyday products including laptops, smart refrigerators and lighting. 

The NOVELDA UWB sensor works by detecting tiny movements made during respiration for perceiving human presence. It is highly sensitive such that human presence can be detected even if subjects are lying under a duvet or wearing several layers of clothing. 

Measuring only 12mm x 12mm, including antennas, NOVELDA Ultra-Wideband Sensor is the smallest and most accurate impulse radar sensor available. It can be completely hidden in a device and can operate through glass, plastic or wood.

“This next generation of human sensors designed for smart home and intelligent building automation will make environments more context-aware to improve interactive experiences, reduce the cost of powering a device when no one is around, and extend screen life by preventing unnecessary backlighting, reducing overall energy consumption,” said Jan-Bjørnar Lund, CEO, NOVELDA.

He added, “Our sensors have been evaluated in challenging real-world conditions and have demonstrated robust performance leagues better than other comparable solutions. UWB is going to drive the next revolution in wireless technology and we believe it will be as widely used as Bluetooth.”

Multiple-use cases for NOVELDA Ultra-Wideband Sensor include touchless-screen displays, lighting and HVAC control and wireless health monitors. NOVELDA UWB is used by customers worldwide in smart homes, building automation and leading consumer electronic devices. 

Examples include Lenovo, which is using NOVELDA Ultra-Wideband Sensor in their premium laptops. In PCs, the sensor enables features such as auto wake-up and auto-lock to increase security and extend battery life, for lighting and HVAC room sensors save significant energy. Other customers use UWB sensors for vital sign detection in sleep monitors.

Ultra-Wideband provides a highly accurate, low-power, robust and secure wireless technology for sensing, positioning, movement and distance. Especially in challenging environments, UWB technology outperforms other technologies such as Passive InfraRed or Time of Flight sensors in terms of accuracy, robustness and security.

Ideally suited for the bandwidth needs, cost, power consumption and physical size requirements for next-generation consumer electronic devices and smart home appliances, UWB wireless sensors can function in the proximity of other radios without interference.

NOVELDA radar technology is a groundbreaking radar system with market-leading reliability in functionality, power use and size compliant with global standards. Demo kits for the NOVELDA UWB X4F103 sensor are available upon request to select customers.

Key Benefits 

  • Customisable sensitivity settings to detect a person walking, standing still, hand gestures or motion sensing and ability to detect submillimeter micro-movements such as breathing for human presence/motion 
  • High-precision ranging for accurate distance measurement and absolute range bounding based on patented impulse radar technology
  • Low power consumption below 2mW, and no co-existence issues with other sensors
  • Wide detection zone for accurate detection with up to 180-degree field of view; zone control can be configured up to 5m depending on the use case
  • No impact on product design; 12mm x 12mm sensor can be hidden in a product and sensor accurately tracks through plastic and glass or layers of clothing

“The True Presence is a game-changing sensor that will enable a new era in building intelligence and energy efficiency,” said Thomas Möller, Managing Director, Steinel. “As a result, we have been able to help our hotel customers improve energy efficiency and cut costs in HVAC by 12%.”

NOVELDA was recently named the 2021 “Best of Sensors” Award winner for the AI and Machine Learning category.
