Product Wiki & Tutorials

Wire the 5 V HLK-LD2410B radar to ESP32 3.3 V logic, check its 256000-baud UART and plan ESPHome presence integration.

24 GHz radar intended for moving/still-target presence sensing; it does not provide a medical heart-rate measurement.
Use regulated 5 V power with common ground. Hi-Link specifies 3.3 V UART/output logic. Check printed pin labels before wiring.
Default UART is 256000 baud, 8N1. Received data uses binary frames; a plain serial text display is not a decoded target measurement.
Detection depends on sensitivity, gates, mounting and nearby motion. The linked Wiki includes a UART byte/OUT check and ESPHome integration guidance.
