ADXL345 Triple Axis Digital Accelerometer Module
Price in Sri Lanka

The device offers a variety of special detection features. Active and Inactive Detection Detects the presence or absence of motion by comparing the acceleration on any axis with a user-set threshold. Percussion detection function can detect any direction of single vibration and double vibration action. Free fall detection function can detect whether the device is falling. These functions can be independently mapped to one of two interrupt output pins. The patented integrated memory management system uses a 32-level first-in-first-out (FIFO) buffer to store data, minimizing host processor load and reducing overall system power consumption.
