User Manual 1. Brief Introduction HLK-LD015-5G is a miniaturized 5.8G radar sensor launched by Hi-Link. The module size is 46*8mm. The module fully integrates 5.8G microwave circuit, intermediate frequency amplifier circuit and signal processor, with high integration and good production consistency. The peripheral is matched with a miniaturized planar antenna, which greatly reduces the overall size while ensuring the performance of the sensor.
HLK-LD015-5G User Manual 3. Input and Output Interface The module reserves 5 pin holes with a PIN distance of 1.2mm. The three PINs VCC, GND and OUT are used by default. If parameters such as distance and delay time need to be modified, they can be flexibly configured through the serial port RX and TX.
°C 6. Sensing time and sensing distance adjustment HLK-LD015-5G requires 3 pins by default, namely VCC, GND and OUT. At this time, the induction delay and induction distance are fixed values. If you need to adjust the induction delay and induction distance and other related parameters, you need to add 2 pins, RX and TX, on the hardware as shown in Figure 3.

Photosensitive detection The module supports photosensitive detection, but photosensitivity can be optional. If photosensitive function is required, a photosensitive diode and regulation resistor can be added to the position shown in Figure 4.
