LD1125H 24GHz mmWave Human Presence Radar Sensor Module (Pre-Soldered)

The LD1125H 24GHz mmWave Human Presence Radar Sensor Module is a compact human presence radar sensor designed to detect occupancy and motion more reliably than basic PIR sensors by using 24GHz millimeter-wave signals to identify presence, movement, and subtle body motion. Built around the LD1125H for smart home automation, lighting control, security devices, robotics, and interactive electronics, this 24GHz mmWave radar helps trigger actions only when a person is actually present. It is well suited for prototyping and embedded integration in Arduino, ESP32, Raspberry Pi, and other microcontroller-based projects where accurate indoor presence detection is needed. The header pins ship pre-soldered, so it works out of the box with no soldering required.
