AT58L4M32-2020 Motion sensor AT58L4M32-2020 5.8GHz User Guide 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.
AT58L4M32-2020 Motion sensor Input and Output Interface Five pinholes are reserved in the module. There are five signal pins, VCC, GND, out, TX and Rx. The pin distance is 2.54mm. If you need to adjust the distance and delay time online, you can rewrite the internal parameters through the communication between TX, RX of UART with AT58MP1T1RS32A. The following table is the definition of each pin ： Pin Name VIN GND OUT TX RX Version 1.
AT58L4M32-2020 Motion sensor Module size and Pin position Figure 2 below is the schematic diagram of module size and pin position. The length and width of the module is 20 mm * 20 mm. By default, there is no pin, and the overall thickness is 2.5 mm. If a pin is required, the default pin height is 12 mm. Figure 2 Module size and pin position of AT58L4M32-2020 Version 1.

AT58L4M32-2020 Motion sensor Photosensitive Detection The module supports photosensitive detection. The sample module does not turn on the photosensitive detection function by default. The position shown in Figure 3 is the photodiode. The photosensitive threshold can be adjusted by changing the photosensitive judgment threshold or tuning the photosensitive resistance. When the photosensitive function is turned on, the radar sensing will be started only when the ambient light is lower than the set value.
AT58L4M32-2020 Motion sensor Detection Pattern The sensing sensitivity of radar sensor can be configured by MCU, and its limit sensing distance is 20 meters. The actual sensing distance can be adjusted according to the needs. The following is the schematic diagram of radar detection range in case of high hanging. If the sensitivity is set higher, the detection range will be correspondingly larger.
