K-Band 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 equipments 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:
● Motion sensor using the 24GHz Microwave Doppler
● Antenna, RF circuit, IF amp, MCU and voltage
   regulator are integrated in a small package
   (14x20.4x8.8mm)
● Communication with PC/MCU is available by UART
   interface and stand alone operation is also
