ATS58LP-2020B 5.8GHz Radar sensor User Guide
Description
ATS58LP-2020B is an ultra-low power 5.8G radar sensor launched by AirTouch. The overall
power consumption is 68uA. The module size is 20mm*20mm, which is equivalent to a 5coin.
，
The sensor uses a self-developed radar sensor chip AT5810S, which integrates a 5.8G microwave
circuit, an intermediate frequency amplifier circuit and a signal processor
，
The chip has a high degree
of integration and good production consistency. The peripheral is equipped with a miniaturized planar
antenna, which greatly reduces the overall size while ensuring the performance of the sensor.The
sensor can be used to detect various scenes of human being or moving target sensing， including
intelligent home, Internet of things, intelligent lighting and other fields，It is especially suitable for
low-power battery-powered scenes such as night lights, solar street lights and wireless cameras.

Five pin holes are reserved in the module, including VCC, GND, OUT, SCL and SDA,
with pin distance of 2.54mm
，
If you need to adjust parameters such as distance and delay time,
you can adjust the specific resistance on the module to select the corresponding gear or use the
external MCU reserved on the module to rewrite the internal parameters
