NOVELDA’s latest UWB radar presence sensor consumes less than 100 µW

NOVELDA has unveiled a new low-power ultra-wideband (UWB) radar presence sensor with a power consumption of under 100 µW and designed to operate on two AAA batteries for up to four years.

We first wrote about NOVELDA in 2021 where we covered their UWB X4 presence sensor capable of detecting submillimeter movements with a power consumption of under 2mW. The company has further optimized the technology and has come up with a 30x5mm module capable of doing the same with 0.1mW power consumption.

The sensor is said to work behind various materials such as plastics, tempered glass, and ceramics, the detection zone size and shape can be adjusted to meet the application requirements, and the device provides accurate angle and distance information.

The new ultra-low power UWB radar presence sensor will mostly be useful for energy/resource savings, lengthening a product’s life cycle, and health monitoring with some of the potential applications including:

• Consumer electronic devices with improved energy efficiency and device performance. For example, an LCD screen lifetime could be extended up to 10 years with the UWB sensor.
• Smart hygiene appliances such as the ones found in public restrooms, for instance, faucets and smart toilets, in order to reduce water consumption.
• Lighting control, security systems, smart door locks, and other building automation use cases such as desk occupancy detection
• Breathing motion detection at a range of up to 10 meters in health monitoring devices.
• Precise distance and angle measurement to multiple targets to estimate the number of people in a specific area.
• Battery-powered appliances that can last up to 4 years with just two AAA batteries

Samples of the new NOVELDA presence sensor will be available in Q3 2023, while the final product will only launch in mid-2024. NOVELDA made the announcement as they are demonstrating a prototype at the Sensors Converge Expo 2023 until June 22. A few more details may be found in the press release.
