...By reducing all data to a single sensors_event_t 'type' and settling on specific, standardized SI units for each sensor family the same sensor types return values that are comparable with any other similar sensor. This enables you to switch sensor models with very little impact on the rest of the system, which can help mitigate some of the risks and problems of sensor availability.

periph is a Go library that unifies hardware I/O on single-board computers and embedded Linux devices, exposing clean interfaces for GPIO, I²C, SPI, UART, PWM, and more. Its philosophy is “no daemon, no codegen”—you link a Go package and speak directly to the hardware via stable abstractions, keeping deployments simple and auditable. The project auto-detects host capabilities at runtime and selects the best driver backend, smoothing over kernel and board differences across Raspberry Pi,...

The libRSF is an open source C++ library that provides several components that are required to estimate the state of a (robotic) system based on probabilistic methods. By applying the factor graph concept, well known from Graph SLAM, libRSF provides a robust solution for many sensor fusion problems. The general idea of factor graphs is to describe the state estimation problem as a graph of nodes (the state variables) that are connected by factors (measurements). The resulting graph optimization problem can be solved by applying non-linear least squares optimization.

Sticky Sidebar ⬆⬇ is a pure JavaScript plugin for making smart and high-performance sticky sidebar, works with the sidebar if it’s taller or shorter than the viewport, is integrated with a resize sensor to re-calculate the dimensions automatically when the size of the sidebar or its container is changed, supports jQuery/Zepto and compatible with Firefox, Chrome, Safari, and IE9+. The source can be found on GitHub.

Attitude Estimator is a generic platform-independent C++ library that implements an IMU sensor fusion algorithm. Up to 3-axis gyroscope, accelerometer and magnetometer data can be processed into a full 3D quaternion orientation estimate, with the use of a nonlinear Passive Complementary Filter. The library is targeted at robotic applications, but is by no means limited to this. Features of the estimator include gyro bias estimation, transient quick learning, multiple estimation algorithms, tuneable estimator parameters, and near-global stability backed by theoretical analysis. ...

...First goal is a full implemenation of the NMEA 0183 protocol 3.0 (without proprietary extensions). The library provides parsers for NMEA sentences, gpsd-like network daemons and data generators for simulation and testing. This allows advanced sensor handling from cellphones/tablets/laptops with GPS up to vehicles/ships with NMEA sensors on board.
