Nisshinbo Micro Devices Inc. Intelligent Microwave Sensors
Nisshinbo Micro Devices Inc. supplies microwave sensor modules for various indoor and outdoor lighting applications
Nisshinbo Micro Devices Inc.'s microwave sensors are intelligent modules that include an internal signal processing MCU and can detect human motion and presence in either outdoor or indoor environments. Due to its unique signal processing and user-friendly interface, the intended detection can be accomplished with simple settings without complicated circuit design or signal processing.
The Nisshinbo Micro Devices Inc. microwave sensors are suitable sensor modules for use in many lighting applications that include outdoor situations like pedestrian traffic and cross walks and energy savings for indoor office or industrial lighting.
The NJR4266 series are Doppler sensors that can detect moving objects. It is an intelligent human motion sensor module that can detect objects moving at low speed like a pedestrian in a short distance range (up to 7 to 14m) and incorporates a 24GHz band microwave circuit, antenna, signal processing circuit, and an MCU in a 17.2mm x 27.3mm x 5.2mm low-profile package. Nisshinbo Micro Devices Inc. proprietary signal processing technology greatly reduces false detection due to environmental noise, achieves stable detection results, and identifies directions of approach and separation. The NJR4266 modules have a user selectable ECO mode function to reduce power consumption.

The NJR4234 series are sensors that can measure the distance to moving and/or stationary objects in the detection area. It is possible to make more advanced and complex settings than the NJR4266.
The NJR4234 can measure the distance to an object such as a pedestrian more than 20 meters ahead and incorporates a 24GHz band microwave circuit, antenna, and signal processing circuit and an MCU in a low-profile package of 38mm x 38mm x 4.2mm. This module is capable of distance measurement and can detect moving or stationary objects by innovative proprietary signal processing.
