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
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 movement direction
(approaching and leaving).
● Low voltage operation and low power consumption
● Sleep mode for reducing power when unnecessary
APPLICATIONs
● Various equipment control by human sensing
