HLK-LD020 5.8G microwave radar module detects human movement by microwave signal reflection. Unlike PIR sensors, it works reliably in dark environments and can be concealed inside non-metal housings. It offers both 2.0mm and 2.54mm pin hole spacing options to match common connector standards. You can configure detection range, trigger delay and light threshold according to your needs. It features low standby power and simple signal output, easy to pair with MCU, relay modules and smart switches. Great for under-cabinet lights, stair lights, sensor switches and all kinds of embedded induction projects. This package includes 10 pieces for bulk evaluation and mass assembly.
