Nisshinbo Micro Devices NJR4267

The NJR4267 is a microwave 24 GHz Doppler sensor module in a small and low profile package with a high sensitivity and range from 20 to 30 meter. Despite its small size, it is an all-in-one module with built-in microwave circuit, antenna, and MCU for control and signal processing. It is equipped with an algorithm that identifies approaching and away moving objects of human bodies as detection targets, enabling customers to shorten their product development time.
