With the advent of the 5G era and the increasing development of AIoT, the intelligent upgrade of human-machine interaction and Internet of Things is ushering in an explosion. The microwave radar human body sensor at the perception layer of the Internet of Things undoubtedly plays an indispensable and important role in the realization of the intelligent scene of the Internet of Things. With the help of microwave radar sensors, people can detect the movement of objects, so as to achieve functions such as people coming and lights going off, intelligent linkage and scene definition, so they are widely used in smart lighting, smart homes, smart home appliances, and smart security And other fields.

But in some special application scenarios, in addition to human motion sensing, people often have higher demands.

To meet these needs of the market side, as the world's leading experts of AIoT sensor chip, Airtouch Technology has officially launched - the lifebeing sensing solutions that can detect human breathing !

Airtouch Technology’s presence sensing solution is developed based on our radar chip AT58MP1T1RS32A (hereinafter referred to as AT5820). AT5820 is the latest fully integrated 5.8GHz radar sensor chip launched by the airtouch. It integrates high-performance radar transceiver and MCU on a single chip. It has rich resources, powerful performance, rich algorithms, and can be interconnected with other main controllers or sensors. It can also be used as a master. Thanks to the chip’s super radar sensing performance and professional signal processing capabilities, our lifebeing sensing solution developed based on AT5820 filters out clutter interference through algorithms. While realizing human motion detection, it can also detect micro-movements and even breathing signal, so as to realize the real human lifebeing sensing.
