NJR4266 series

Description

NJR4266 is intelligent human motion sensor module that can detect objects moving at low speed like a pedestrian in a short distance range (7 to 14 m) by itself and it incorporates a 24GHz band microwave circuit, antenna, signal processing circuit, and also MCU in a 17.2 x 27.3 x 5.2 mm low profile package.

Features

Motion detector using the 24GHz Microwave Doppler

Low-profile package

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

Low power consumption - ECO mode: Minimum 1.9 mA @ 3.3 V

Selectable from UART and digital output / analog setting

4 kinds of antenna types

Signal processing software for the steady sensing
