ATS58-2020 5.8GHz User Guide
Description
ATS58-2020 is a miniaturized 5.8G radar sensor launched by AirTouch
，
The module size
is 20*20mm, the size is equivalent to a coin,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.Especially in the field of lighting, it has
been widely used in standard lighting products such as induction bulbs and T8 tubes.

Input and Output Interface
The module reserves 5 pin holes with a pin distance of 2.54mm. By default, three pins,
VCC, GND and out, are used
，
If you need to adjust the distance, delay time and other
parameters, you can use the UART port RX and TX to flexibly configure them. For scenarios
without upper computer, you can also use RX and TX as I / O ports to adjust the parameters
，
The following table describes the definition of each pin:
