Automatic Motion Detection and Distance Measure Using Doppler Radar

Abstract

The proposed device is a versatile and multi-functional system that uses an HB100 Doppler radar sensor and Arduino microcontroller to detect motion, measure velocity, and distance. The device is capable of detecting motion in real- time, measuring the velocity of the object, and calculating the distance between the object and the sensor. The HB100 Doppler radar sensor emits a microwave signal that reflects off the object and returns to the sensor. By analyzing the changes in frequency of the reflected signal, the radar can determine the speed and direction of the object. The sensor is connected to an Arduino microcontroller, which receives the digital signal from the sensor and processes it to determine the presence, velocity, and distance of the object. The proposed device offers several benefits, including increased accuracy and efficiency compared to other motion detection systems. The device can be used in a variety of applications, such as security systems, traffic monitoring systems, and industrial automation. The device's ability to detect motion, measure velocity, and calculate distance can also be used to monitor and analyze data for further applications.
