1.Description
ATS58-1818 is a miniaturized 5.8G radar sensor launched by AirTouch Intelligent. The
module size is 18 * 18mm and the size is equivalent to a 50 cent coin. The sensor uses AirTouch
self-developed radar sensor chip AT5810. Because AT5810 has integrated 5.8G microwave
Circuits and IF amplifier circuits, high integration and good production consistency, with small
doubly-fed antennas in the periphery, which greatly reduces the overall size while ensuring the
performance of the sensor. The sensor can be used in various scenarios where human presence or
moving targets are sensed, including smart home, Internet of Things, and intelligent lighting.
Especially in the lighting field, it has been widely used in standard lighting products such as
induction bulbs and T8 lamps.
