MaxBotix Inc., engineers have written a full evaluation that can be seen here that covers proper mounting of a sensor to avoid acoustic interference from the propellers, and corrections for electrical noise. Through this evaluation, we have identified the sensors with the best operation for this application. To read about this application, click here.
Sensors For All Environments
This is a great choice for users who may fly in rain or inclement weather. This sensor has the same pin interface as the MB1240, making it a perfect drop-in replacement.
Ultra-compact, lightweight IP67 rated sensors that is perfect for users that fly UAVs in inclement weather. Great for weight sensitive UAVs, this sensor only weighs 18 grams.
Sensors For Protected / Indoor Use
The MB1240 is recommended for powerful UAVs. During UAV testing, our engineers have seen this sensor demonstrate the best performance. This sensor has great resistance to the acoustic and electric noise present on many UAV platforms.
Uses the I2C communication protocol. Similar function to the MB1240.
The MB1230 is great for UAVs that require slightly more sensitivity than the MB1240 offers.
Uses the I2C communication protocol. Similar function to the MB1230.
The MB1220 is a great balance between noise rejection and small target detection. This is a great starting point for UAV operators confident in their electrical engineering ability. A clean, stable power supply and proper ADC reference (or digital input) will be required. Users should test propellers and motors for acoustic noise at 40kHz. (Recommended SPL levels should not exceed 70db at 40kHz).
