5.8Ghz low power radar sensor Radar sensor AT58L4MD-2020 5.8GHz Radar sensor User Guide Description AT58L4MD-2020 is an low power 5.8G radar sensor launched by AirTouch. The overall power consumption is 9mA. The module size is 20mm*20mm, which is equivalent to a 5coin.， The sensor uses a self-developed radar sensor chip AT58MP1T1RD, which integrates a 5.
5.8Ghz low power radar sensor Radar sensor Pin Name VCC Function Note LDO is not attached by default, it can be directly powered by Power supply 2.8~4.8V. If the power supply voltage exceeds 5V, an LDO needs to be added. At this time, the power supply VCC is 5~12V. GND OUT SCL SDA Version 1.0 Ground PIN Output control The output signal is high and low level (0V/3.3V).
.8Ghz low power radar sensor Radar 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.
5.8Ghz low power radar sensor The hold time and detection area The AT58L4MD-2020 pin has an IIC signal pin. When debugging, the host computer can be used to adjust the delay, sensitivity and other parameters through the IIC; there is also a reserved MCU position on the module, and the sensing distance ， Delay and other parameters of the radar can also be initialized through the MCU on the module.
5.8Ghz low power radar sensor start the sensing function. When testing the radar performance alone, the photodiode can be covered with black tape to avoid the photosensitive effect affecting the radar sensing function. Radar sensor Power on Sequence The module has a power-on self-check function, that is, after the module is powered on, the OUT pin first outputs a high level, and then outputs a low level after a delay of 3S, and enters the normal induction mode after a low level delay of 0.
5.8Ghz low power radar sensor Radar sensor Detection Pattern The sensing sensitivity of the radar sensor can be configured by adjusting the resistance, and its limit sensing distance is 6~8 meters, and the actual sensing distance can be adjusted appropriately according to 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.
