ADXL345 Triple-Axis Accelerometer Sensor Module - I2C/SPI Interface
The ADXL345 digital accelerometer module provides high-resolution (±2g to ±16g) 3-axis acceleration measurement via I2C or SPI interface, compatible with 3.3V/5V systems like Arduino, Raspberry Pi, ESP32, and STM32 for tilt sensing, motion detection, and impact analysis.
Features
- High-resolution digital 3-axis accelerometer with user-selectable ranges from ±2g to ±16g.
- Ultra-low power operation: 40µA in measurement mode and 0.1µA in standby.
- Integrated intelligent motion detection features: free-fall, single/double-tap, and activity/inactivity sensing.
- Dual digital interface support: I2C and SPI for flexible microcontroller integration.
- Robust 10,000g shock survival rating and wide operating temperature range (-40°C to +85°C).

The ADXL345 is a low-power, 3-axis MEMS accelerometer providing digital output via I2C or SPI serial interfaces. It measures both static acceleration (for tilt sensing) and dynamic acceleration (from motion or shock) with a high resolution of up to 13 bits (4 mg/LSB). The module includes an onboard RT9161 voltage regulator for stable 3.3V/5V operation in noisy electrical environments.
Advanced embedded functions such as free-fall detection, tap sensing, and activity monitoring can be mapped to hardware interrupt pins, minimizing host processor load. A built-in 32-level FIFO buffer further reduces system overhead by storing data samples. Its robust design ensures reliable performance in industrial, consumer, and embedded applications.
