Frequently Asked Questions

What is the operating voltage range for the HLK-LD2410 sensor?

The HLK-LD2410 operates on a wide voltage range of 5 to 12 volts DC. This makes it compatible with common 5V microcontroller systems like Arduino and ESP32, as well as standard 12V power supplies often used in security and automation installations.

How do I communicate with and configure the HLK-LD2410 module?

The module communicates via a UART (serial) interface. You can connect its TX and RX pins to a microcontroller's serial port to send configuration commands and receive detection data. The protocol is documented by Hi-Link, and configuration typically involves setting sensitivity, detection zones, and output modes.

Can this sensor detect stationary (non-moving) humans?

Yes, the HLK-LD2410 uses 24GHz FMCW radar technology, which is capable of detecting both moving and stationary human presence, unlike traditional PIR sensors that only detect motion. This makes it suitable for applications requiring continuous occupancy monitoring.

What is the effective detection angle and range?

The sensor has a horizontal detection angle of up to ±60 degrees (a total of 120 degrees) and a maximum detection distance of 5 meters. The actual range can be configured via software to define specific detection zones and sensitivity thresholds.
