LD2410 24GHz Human Presence Sensing Module

SKU: SEN0557

LD2410 is a 24GHz human presence sensing radar module using FMCW tech. It detects moving/stationary humans, calculates target distance, and resists environmental factors (temp, humidity, etc.). It penetrates materials, works in enclosed shells, offers up to 6m sensing distance (0.75m resolution), and supports UART/GPIO output. Users can configure parameters via serial. It’s applied in smart light control, ad screen wake-up, UV control, home security, etc.
