UAV Ultrasonic Sensors – Measure Distance and Proximity

UAV Ultrasonic SensorsEasily complete your application with our UAV Sensors.

“What goes up, must come down.” One of the biggest considerations for how much time a UAV spends in the air is weight. This means that every ounce affects the UAV. We design our UAV ultrasonic sensors to be high performance, small, compact, low-cost, easy-to-use and lightweight. Our recommended ultrasonic sensors for UAVs weigh approximately 5.8 grams.

What is more fun?

Flying a UAV autonomously or coding how to read an ultrasonic sensor?

We took the complicated integration out so that you can add cool features to your UAV such as GPS navigation and cameras for aerial photography.   Our sensors include multiple outputs for simple integration. Our interfaces include Analog Voltage, Pulse Width, Serial Data, and I2C. Many popular modules, including the APM 2.6, already have sensor libraries for faster integration.

Simple and Reliable Interface

Our free-running operation simplifies user code and setup. Our UAV ultrasonic sensors are designed to be low-cost so users can implement several ultrasonic sensors onto a single airframe. This gives the UAV a wider field of view using the data output from the ultrasonic sensors. Customer satisfaction is our first priority — including product selection, design, development, ordering, shipping, and technical support. Ordering is easy through our online store or customers can purchase from one of our many distributors worldwide. MaxBotix Inc. offers hundreds of easy-to-use ultrasonic distance sensors across 18 product lines.

Using UAV Ultrasonic Sensors on a Multi-Copter

MaxBotix Inc., engineers have written a full evaluation that covers correct sensor mounting and installation. The best MaxSonar UAV ultrasonic sensors were identified in the evaluation and recommended. This tutorial is designed to help you understand the key elements in building a successful Multi-Copter. Elements such as air turbulence, propeller acoustic noise, grounding, and power, conducted electrical noise, radiated electrical noise and frame vibration.

MaxSonar Operation on a Multi-Copter

MaxBotix Inc., sensors have been successfully used on a number of multi‑copters. Multi‑copters are also called UAVs, rotorcraft, quadrotor helicopters, or quadcopters. Many users have had issues getting the sensors to operate reliably. Sensor operation during a flight on a quad‑copter is a challenging environment for an ultrasonic sensor to operate reliably.

Sensor operation during flight on a quad‑copter is a challenging environment for an ultrasonic sensor to operate reliably. The most obvious issue is the amount of wind turbulence the ultrasonic wave must travel through.
