Abstract: Vehicles today are relying more on technologies to bring about fully autonomous features. The conventional wirings within are being simplified into a network of electronic components, and ...

Abstract: This paper presents design and implementation of an ultrasonic sensor based walking stick for visually impaired person. An ultrasonic sensor module, HC-SR04 is used for obstacle detection in ...

An Arduino library for the Hi-Link HLK-LD2450 24Ghz FMCW radar sensor. This sensor is a Frequency Modulated Continuous Wave radar, which makes it good for presence detection and has some interesting ...

Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...
