Rev.05e July 11, 2017 NJR4265R - 1 - NJR4265R series 24GHz Microwave Intelligent Motion Sensor for Short Distance, Low Speed Applications NJR4265R is intelligent motion sensor that is designed for the sensing of short distance low speed movement object of pedestrian etc. The steady sensing of moving object is realized by embedded software. It is suitable for the built-in use of the sensing function to various equipment as all functions are integrated in a small package and it can easily control from PC/MCU by UART interface. Further, stand-alone operation is also possible. Features: Applications: Various equipment control by human sensing Motion sensor using the 24GHz Microwave Doppler Energy saving management Antenna, RF circuit, IF amp, MCU and voltage Entrance and exit management regulator are integrated in a small package Safety and Security (14 x 20.4 x 8.8mm) Communication with PC/MCU is available by UART interface and stand-alone operation is also possible Signal processing software for the steady sensing Enhancing the signal from movement object and decreasing random noises Decreasing the mutual interference between sensors Identification of direction for movement object (approaching and leaving). Low voltage operation and low power consumption Sleep mode for reducing power when unnecessary Functional Brock diagram: Rev.05e July 11, 2017 NJR4265R - 2 -
