Radar module with LDS2420, working at 24 GHz frequency, equipped with transmission and reception antennas integrated directly on the PCB. It uses radar distance measurement technology, using millimeter waves, and advanced signal processing technology from the S3 series chips to accurately detect movement, micro-motion and the presence of the human body.
The module is ideal for detecting human presence in indoor scenarios, updating the detection results in real time and having a maximum detection distance of 8 meters for people in motion.
Thanks to the use of radar, this module detects both human bodies and objects, as long as they are in motion.
The HLK-LD2420 is equipped for simple configuration, supporting adjustment of detection distance range, sensitivity and detection refresh time. It is compatible with GPIO and UART interfaces for easy integration and is preloaded with configurations for detecting human presence.

Eu am reusit sa-l conectez OT1 (TX) la RX si RX la TX (al meu a venit cu versiunea 1.5.6).Totul conectat la un esp32 devkit si am scris totul cu esphome pentru a fi integrat direct in HomeAssistant. Pot spune ca are o precizie foarte buna, sunt multumit ! Initial am primit un produs defect insa oamenii astia-s faini rau si au trimis un altul, gratuit. Multumesc ! Apreciez !
