Overview: NJR4234BW series 24GHz Microwave Intelligent Distance Measurement Sensor Module for Middle Distance (20 meter) with Low-profile The NJR4234BW is a sensor module that can measure the distance to a moving object and/or stationary object more than 20 m ahead and incorporates a 24 GHz band microwave circuit, antenna, and signal processing circuit in a low profile package of 38 x 38 x 4.2 mm. As a sensor capable of distance measurement using microwave, it is possible to detect moving objects by innovative proprietary signal processing, even to detect stationary objects, and also has the function to calculate and output the distance to the objects in indoor and outdoor environments. In addition, it has the unique algorithm to prevent radio interference, possible to use multiple sensors under the same location. It can be used as a sensor front end with built-in primary signal processing for distance measurement. In addition, since it can be easily connected to other equipment via the UART interface, it can be used in a wide range of applications.
