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 ...
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 ...
Abstract: A new analytical method for 3-D target localization based on a four-element ultrasonic sensor array is proposed. In the sensor array, with the consideration of good real-time performance, ...
This is a library for the laser particle sensor module PM2005 manufactured by Wuhan Cubic Optoelectronics. The PM2005 module counts airborne particles of different sizes in catagories of 0.3, 2.5, and ...
