SUI04
Ultrasonic Sensor of Overall Obstacle Avoidance
Adaptable to Multirotor

Technology of Hardware and Software Dual Filters,
30ms Extreme Fast Response
0.4cm Detecting Precision, Accurate Obstacle Avoidance without Delay
Transeiver with 60° Beam Angle and Zero Fade Area
30ms Extremely Fast Response
With the integrated 32-bit processor and a breakthrough of hardware and software dual filters technology adopted, SUI04 ensures accuracy and realizes the 30ms fast response, solving the common delay problem of other products. This function is helpful for flight operations such as agricultural drones, detecting the height in real-time and feedback when there are obstacles and protecting both operator and drone.
Compatible with all RadioLink APM series flight controller. Before using the overall obstacle avoidance function of SUI04, the flight controller’s firmware to the Copter V3.5.7 version should be upgraded.

60° Beam Angle, Overall Synchronous Avoidance

60° beam angle ensures environment detection and obstacle sensing in real-time. Connect SUI04 with all RadioLink APM flight controllers, via the I2C expansion board to realize obstacle avoidance in 6 directions* synchronously to guarantee a safer flight.
High Precision of 0.4cm
With 0.4cm detecting accuracy and zero fade area, SUI04 can quickly spot barriers.
