NJR4267 24GHz band Doppler Sensor Module

The NJR4267 Series 24GHz Doppler Motion Detector Module is a compact microwave sensor designed for motion detection in security and monitoring applications. With a detection range of up to 30 meters and a wide detection angle of up to 110°, it is ideal for intrusion detection, perimeter monitoring, security lighting, and touchless access control.

Its all-in-one design integrates the antenna, microwave circuit, and MCU, while built-in signal processing helps reduce false alarms. The module features low power consumption of 1.5 mA @ 3.8 V and measures only 17.2 × 25 × 3.1 mm.
