Sensor Modules

24GHz Motion Detector Modules –Digital Output Type–

NJR4265 series

Motion detector using the 24GHz Microwave Doppler
Antenna, RF circuit, IF amp, MCU and voltage regulator are integrated in a small package
Low voltage operation and low power consumption
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)
Communication with PC/MCU is available by UART interface and stand-alone operation is also possible
