NJR4267 series
24GHz Motion Detector / Radar Sensor Doppler Module, Digital Output / High Sensitivity Type
The NJR4267 is a microwave 24GHz Doppler sensor module in a small and low profile package measuring 17.2 x 25 x 3.1 mm. Despite its small size, it is an all-in-one module with built-in microwave circuit, antenna, and MCU for control and signal processing.
Features
- Motion detector using the 24GHz Microwave Doppler
- Antenna, RF circuit, IF amp, MCU and voltage regulator are integrated
- Equipped with an optimal algorithm for detecting moving objects
- Supports UART/PWM/CMOS level output interface
- Low power consumption due to intermittent operation
- Antenna angle (half width) V plane 80°/H plane 110°
- Small and low profile package
