Product overview
The RadioLink SUI04 is an ultrasonic sensor for multirotor obstacle avoidance and real-time height detection, including agricultural drone operations. Its single-detector transceiver incorporates a 32-bit processor and hardware and software filtering. The body measures 20 × 22 × 19 mm (0.79 × 0.87 × 0.75 inches) and weighs 8g (0.28oz), defining the sensor’s physical integration footprint. Detection specifications include a 60° beam angle, 0.4cm accuracy, 30ms response and zero fade area. These figures reflect favorable, closed-environment conditions with an unobstructed wireless signal; actual results may vary with environment, usage and firmware version.
Integration with RadioLink APM series flight controllers through an I2C expansion board supports synchronous obstacle avoidance forward, backward, left, right, upward and downward. Overall obstacle avoidance with PIXHAWK and Mini PIX requires upgrading the flight controller firmware to Copter V3.5.7. Six-direction operation carries the same favorable, closed-environment measurement conditions and variability with environment, usage and firmware version. The supplied package contains one SUI04 sensor, one PIXHAWK I2C wire, one connection wire for CrossRace, CrossFlight, Mini Pix or an I2C Transfer Board, and one packing bag. This is a sensor accessory package for aircraft integration.
