Overview

The TFSLOT01 sensor is a next-generation airspeed sensor designed for UAVs, leveraging the Venturi effect for superior performance at low airspeeds. This clog-resistant design is coupled with an integrated 9-axis IMU to be ready for additional diagnostic capabilities like vibration monitoring and angle-of-attack measurements.

This product is fully open-source, with a customizable 3D-printed case for seamless integration into UAV designs. Whether you're a developer, researcher, or enthusiast, the TFSLOT01 provides reliability, adaptability, and advanced functionality.

Key Features

Clog-Resistant Design: Venturi-based measurement reduces clogging risks, ideal for low-speed UAVs.
Integrated IMU: Features a 9-axis IMU (magnetometer, accelerometer, gyroscope) for advanced diagnostics.
Customizable: 3D-printed case can be adapted to specific applications.
Weatherproof Build: IP42-rated for reliable operation in diverse conditions.
Enhanced Resolution: Optimized for speeds below 10 m/s.
Direct Integration: No need for additional tubing, reducing maintenance concerns.

Technical Specifications

Parameter	Value	Description
Airspeed Range	0 - 48 m/s	Assumes air density of 1.29 kg/m³
Dimensions	35 x 40 x 35 mm	Default 3D-printed case
