Good range, tricky config
Detection range is solid up to 5 meters. Configuration software took some time to understand but works well once set.

Perfect for Bathroom Lights
Installed this to control bathroom lighting. No more lights turning off while bathing. Very reliable.

Solid Module
Good build quality. UART communication is straightforward. Wish the antenna cable was included for remote mounting.

Great for Home Automation
Works perfectly with ESPHome. Detects me sitting still at my desk which PIR sensors miss.

Accurate Presence Detection
Finally a sensor that knows I'm in the room even if I'm not moving. Voltage input is stable at 5V.
Q: Is this compatible with ESP32?
A: Yes, it uses UART TTL which works perfectly with ESP32 GPIO pins.
Q: Can it detect motion through walls?
A: No, mmWave signals cannot penetrate metal or thick concrete walls effectively.
Q: How do I update the firmware?
A: You can use the official configuration tool via UART connection to flash new firmware versions.
Q: Does it require external antenna?
A: No, it has an onboard PCB antenna. External antenna pads are available on some variants but not needed for standard use.
Q: What is the maximum detection distance?
A: The LD2410C supports up to 6 meters depending on configuration and environment.
