Description
AT58L4M32-2020 is a 5.8G radar sensor with low power consumption, which is
launched by AirTouch. The power consumption is about 20mA, and the module size is
20mm * 20mm. The sensor adopts the self-developed radar induction chip
AT58MP1T1RS32A, which integrates a 5.8GHz microwave circuit, an intermediate
frequency amplifier circuit, a signal processing circuit and a powerful MCU, with high
integration and good production consistency, A miniaturized path antenna is used in the
periphery to ensure the performance of the sensor and greatly reduce the overall
size.Because of its low power consumption,low cost and compliance certification, the sensor
has been widely used in intelligent lighting, smart home and other fields. This scheme is the
first choice for upgrading the traditional non fixed frequency scheme, and also the preferred
scheme for improving the performance of traditional 5.8G microwave induction products.
