Description


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
