GYUS42 i2c Pixhawk APM Ultrasonic Distance Measurement Module What it does Ultrasonic distance sensing module designed for flight control. The GYUS42 provides accurate distance measurements to support low-altitude flight functions on Pixhawk and APM systems via an i2c interface. Single-piece module that simplifies installation and wiring in UAV setups. Why you need it Improves flight safety and control by providing reliable close-range distance data for altitude hold, landing, and obstacle awareness. Reduces integration time and wiring complexity when adding distance sensing to Pixhawk or APM-based aircraft. Delivers consistent readings that help flight controllers make better real-time decisions during critical flight phases. Key benefits and problem solving Seamless compatibility: Native i2c support and explicit design for Pixhawk and APM flight controllers minimize configuration issues and support straightforward connection to existing flight stacks. Simplified integration: The single-piece form factor consolidates sensing hardware into one module, reducing points of failure and easing mounting and wiring. Reliable ultrasonic sensing: Uses ultrasonic technology to provide dependable distance measurements for low-altitude and short-range applications where optical sensors can struggle (e.g., low light, particulate conditions). Important attributes Function: Ultrasonic distance measurement for flight control applications (altitude hold, landing assistance, obstacle/terrain sensing). Compatibility: Designed to work with Pixhawk and APM flight control systems over i2c. Size and installation: Single-piece module for compact, straightforward mounting and reduced wiring complexity. Construction: Built for use on unmanned aircraft where a consolidated sensor helps keep the airframe tidy and dependable. Performance: Accurate and stable short-range distance data suitable for routine flight-control tasks; designed to integrate into real-time control loops on Pixhawk/APM platforms. Practical use scenarios Precision landing: Provide reliable low-altitude distance information to improve automatic landing accuracy and reduce hard touchdowns. Obstacle avoidance during approach: Supplement higher-level navigation with short-range sensing to detect nearby obstacles during takeoff, landing, or low-speed maneuvers. Terrain following and inspection flights: Maintain consistent altitude above varying ground profiles for close-proximity inspection or mapping missions. Integration tips Connect via the i2c port on your Pixhawk or APM controller and configure the sensor in your flight stack according to standard ultrasonic sensor settings. Mount the module where it has an unobstructed acoustic path to the ground or target surface for best results. Model GYUS42: i2c Pixhawk APM Flight Control Ultrasonic Distance Measurement Module
