Product Introduction

The BDS450 is a Bluetooth-enabled dynamic attitude sensor offering excellent performance at a competitive price. It is widely applicable to equipment requiring high dynamic balance, such as model aircraft, robots, agricultural machinery, construction vehicles, and forklifts. By integrating a three-axis accelerometer, a three-axis gyroscope, and a temperature compensation algorithm, combined with Kalman filtering technology, this product outputs accurate attitude data in real time. It maintains excellent stability and response speed under all attitude conditions, making it widely used in various motion attitude monitoring scenarios.

In addition to attitude data, the product also provides raw measurement information such as three-axis acceleration and three-axis gyroscope readings, and supports modification of operating parameters and expansion of system functions, facilitating adaptation to various application platforms. This product uses a Bluetooth 5.1 wireless transmission solution, adheres to the BLE protocol, and integrates 2.4GHz adaptive frequency hopping technology, achieving a line-of-sight transmission range of up to 40 meters in unobstructed environments. It also supports BLE DFU Bluetooth wireless firmware upgrades, effectively improving the flexibility and convenience of deployment in industrial settings.

1) Accuracy: Refers to the root mean square difference between the measured value and the actual angle error after multiple angle measurements (>16 times) under normal temperature conditions. 2) Zero-point temperature coefficient: Refers to the rate of change of the sensor's reading relative to normal temperature within its rated operating temperature range when the sensor is at zero. 3) Sensitivity temperature coefficient: Refers to the rate of change of the sensor's full-scale reading relative to its full-scale reading at normal temperature within its rated operating temperature range as a percentage of temperature.
