NJR4267 series

24GHz Motion Detector / Radar Sensor Doppler Module, Digital Output / High Sensitivity Type

The NJR4267 is a microwave 24GHz Doppler sensor module in a small and low profile package measuring 17.2 x 25 x 3.1 mm. Despite its small size, it is an all-in-one module with built-in microwave circuit, antenna, and MCU for control and signal processing.

Features

- Motion detector using the 24GHz Microwave Doppler

- Antenna, RF circuit, IF amp, MCU and voltage regulator are integrated

- Equipped with an optimal algorithm for detecting moving objects

- Supports UART/PWM/CMOS level output interface

- Low power consumption due to intermittent operation

- Antenna angle (half width) V plane 80°/H plane 110°

Small and low profile package
