Page 3: Brief Introduction
HLK-LD012-5G User Manual 1. Brief Introduction HLK-LD012-5G is an ultra-low power 5.8G radar sensor launched by Hilink Electronics, with an overall power consumption of about 68uA. The module size is 20mm*20mm. The module fully integrates 5.8GHz microwave circuit, intermediate frequency amplifier circuit and signal processor.
Page 4: Module Size And Pin Position
HLK-LD012-5G User Manual The module reserves 5 pin holes, with a total of five signal PINs VCC, GND, OUT, P2 and P3. The PIN distance is 2.54mm. If you need to tune the distance and delay time and other parameters, you can hang or pull down P2 and P3.

5. Sensing time and sensing distance adjustment The P2 and P3 pins on the HLK-LD012-5G module are used to select different sensing distances and delay gears; P2 is used to adjust the sensing distance, which can be provided with the 3 resistors (th0, th1, th2) reserved on the module 16 different sensing distance options.
