SENSORS
For example, the BGT60TR13C model has one transmitting and three receiving antennas. The L-shaped antenna arrangement allows horizontal and vertical angle measurements. The extremely high accuracy enables motion detection in the sub-millimeter range. The radar sensor is used, for example, for vital data acquisition in consumer electronics.
The BGT60LTR11AIP is a 60 GHz Doppler radar sensor with an integrated transmitting and receiving antenna and integrated motion and direction detectors. It supports multiple modes of operation, including a fully autonomous mode that requires no software or hardware design. In autonomous mode, the radar can detect a human at a distance of up to seven meters, consuming less than 5 mW. This makes the radar sensor ideal for motion detection, such as in smart lighting or climate control, automatic door opening or contactless switches, and smart security and alarm systems, including IP cameras. The BGT60UTR11AIP is the latest member of the BGT60 family and, at just 4.05 mm

Advantages of radar sensors •
•
They are compact, thus enabling the development of IoT systems with relatively small sizes.
They are robust and operate in a variety of environmental and climatic conditions. Their operation is not significantly affected even by temperature fluctuations or lighting conditions.
•
They transmit RF signals at high frequencies (24 or 60 GHz) that penetrate most materials e.g. plastic, glass, and wood. As a result, they provide accurate readings even for objects behind walls or obstacles and can be concealed under product covers or packages.
They offer high measurement sensitivity and can detect very small movements. This means they can be used to record vital data.
They consume relatively little power, enabling energy-efficient IoT applications. Battery-powered devices can operate for a very long time on just one battery.
Hidden Technologies Transforming
Vehicle Safety and Comfort In today’s modern cars, many features are designed to support drivers on their journeys all over the world. Working in the background and invisible to most, some of these hidden components provide us with increasing comfort and safety no matter the driving conditions. EU regulations are becoming stricter with new 2022 regulations for advanced safety systems aiming to improve the safety of both occupants and vulnerable road users. Ultimately, technology will play a key role in achieving the EU’s long-term goal of moving close to zero fatalities and serious injuries by 2050.
