sonicdisc | A 360 ultrasonic scanner

sonicdisc is a C++ library typically used in Internet of Things (IoT), Arduino applications. sonicdisc has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

SonicDisc is a sensor that allows you to sense your surroundings. It utilizes 8 ultrasound sensors (HC-SR04) placed at 45 angle from each other, that can measure distances from practically every direction. It can be used in hobby-grade automotive applications, e.g. autonomous driving, obstacle detection etc or wherever quickly determining surrounding distances is relevant. The sensor transmits the collected data over I2C and uses a separate line to signal, with a short pulse, the existence of a new set of measurements. It can be mounted on top of an Arduino UNO or used standalone. Due to the nature of the HC-SR04 sensors, the measurements can be noisy, therefore it is suggested that they are filtered. A basic Arduino example that receives and filters the incoming data can be found in examples/SonicDiscReader. You can find the software running on the SonicDisc in firmware/, the PCB design in Eagle CAD format inside hardware/ and more sample applications using the SonicDisc in examples.
