Overview: NJR4266 series 24GHz Microwave Intelligent Motion Sensor for Short Distance, Low Speed Applications with Low-profile and Low-power-consumption NJR4266 is intelligent human motion sensor module that can detect objects moving at low speed like a pedestrian in a short distance range (7 to 14 m) by itself and it incorporates a 24 GHz band microwave circuit, antenna, signal processing circuit, and also MCU in a 17.2 x 27.3 x 5.2 mm low profile package. Signal processing of original technology greatly reduces false detection due to environmental noise, achieves stable detection results, and identifies directions of approach and separation. And also it has a function to reduce power consumption by sensitivity setting. It has multiple antenna types so that users can select the optimum detection angle according to the application, and has UART and standalone (digital output / analog range setting) as interface type.
