Shenzhen Mingjiada Electronics Co., Ltd. has long specialised in the supply and recycling of high-performance electronic components. We are now supplying and purchasing the ADXL345 three-axis digital accelerometer for customers worldwide—a classic MEMS motion sensor developed by Analog Devices (ADI) that is widely used in critical applications such as drone flight control, attitude reference systems and vibration monitoring.
I. ADXL345: A Three-Axis Accelerometer Designed for UAV Flight Control
The ADXL345 is a small, thin, ultra-low-power three-axis digital accelerometer housed in a compact 3mm × 5mm × 1mm LGA package, making it ideal for UAV platforms where weight and space are critical considerations. Its key specifications include:
Measurement range: Selectable ±2g, ±4g, ±8g or ±16g, offering flexible adaptation to different flight conditions;
High resolution: Up to 13-bit resolution, maintaining a scaling factor of 4 mg/LSB across the entire g range;
Digital output: 16-bit two’s complement format, accessed via I²C or SPI (3-wire/4-wire) digital interfaces;
Ultra-low power consumption: as low as 23 µA in measurement mode and just 0.1 µA in standby mode;
Wide operating temperature range: −40°C to +85°C, suitable for harsh outdoor flight environments;
High shock resistance: 10,000g shock resistance, easily withstanding drone take-offs, landings and accidental impacts.
Thanks to these features, the ADXL345 not only measures static gravitational acceleration to support tilt sensing, but also accurately captures dynamic acceleration changes caused by motion or impact, making it an ideal choice for realising drone attitude control and condition monitoring.
II. Typical Applications of the ADXL345 in the Drone Sector
Drone flight control systems require real-time acquisition of the aircraft’s attitude angles (pitch, roll and yaw) and motion status. Thanks to its high resolution and low noise, the ADXL345 performs particularly well in the following scenarios:
1. Flight Controller Attitude Estimation and Stabilisation Control
The three-axis acceleration data provided by the ADXL345 can be fused with data from sensors such as gyroscopes (e.g. the ITG3200). Through algorithmic calculations, the drone’s attitude angles are determined, helping the flight control system maintain stable flight. In open-source drone systems such as Paparazzi, the ADXL345 has been widely integrated into IMU (Inertial Measurement Unit) modules.
2. Vibration monitoring and propeller fault detection
Drones are subject to varying degrees of airframe vibration during flight. Research indicates that the ADXL345 can be used to collect drone vibration data in real time and, through classification models, effectively distinguish between healthy propellers and those with various faults. Its training accuracy rate of over 93 per cent fully demonstrates its viability in low-cost, highly reliable vibration monitoring solutions.
3. Auxiliary Navigation in Low-Visibility Environments
Under low-visibility conditions such as dense fog or smoke, data fusion between the ADXL345 and sensors such as LIDAR can assist the drone in maintaining its navigation capabilities during critical flight conditions, significantly enhancing the margin of flight safety.
