Tyto Robotics demonstrates how to connect analog sensors to Flight Stands, provide use cases that highlight the benefits of additional sensors, and some of the challenges that may be faced during tests.
A thrust stand is essential for testing your propulsion system’s thrust, torque, RPM, and efficiency. Integrating sensors into your tests adds another layer of optimization that can take your performance to the next level.
In the unmanned industry, it is well documented that collecting data from external sensors can be challenging. To address these issues, the company has developed a new software feature called “Input Transformations.” This feature allows you to connect external analog sensors to all our Flight Stand products, so you can seamlessly integrate sensor data with your propulsion readings.
Connecting Sensors to Flight Stands
Enhance your unmanned aerial vehicle (UAV) testing by incorporating external sensors into your Flight Stand setup. This guide demonstrates using a sound sensor to optimize propeller noise levels, crucial for quieter flight operations.
Sound Level Measurement
We’ll measure decibel output from a propulsion system (Xoar 26-inch propeller + AXI 8110 motor) using a SEN0232 sound meter connected to Flight Stand 15 Pro. This device operates on 5V input, measuring 30-130dBA range.
Connection Steps:
- Ensure Flight Stand is USB-connected
- Access Input Transformations tab
- Create new transformation
- Name sensor (e.g., “Sound Sensor”)
- Choose unit type or enter “dB”
- Assign voltage input to variable “a”
- Input conversion formula (e.g., a * 50)
- Set system limits based on specifications
- Save configuration
- Navigate to Powertrain Mappings
- Select “Transformations – Sound Sensor”
- Begin testing as usual
Sensor data will be included in exported CSV files. Analysis example: At 1500μs throttle and 1099.45 RPM, system generated 76.18 dB noise.
