ADXL345 is a small, slim, low- three-axis accelerometer, on high Up to +/- 16 g acceleration for high resolution (13 digits) measurement. Number of digital outputsAccording to the 16-bit binary complement ,Via SPI (3-wire or 4-wire), or access I2C digital interface.ADXL345 suitable for mobile equipment applications. It can skew detection applications Measure the static gravitational acceleration, and to measure the dynamics of movement or impact causes the effect Speed. It has a high resolution (4 mg/LSB), measuring approximately 0.25 tilt Angle changes. ADXL345 digital outputs, such as the time of acceleration, without the need for Analog to digital conversion, saves system cost and board space.The device detection offers a variety of special features. and inactive detection capabilities throughCompare any acceleration on axis with the set by the user to detect the presence of games Move takes place. Dan percussion test detects any direction and dual vibration To make. Free detection can detect whether the device is dropped. These Features can be independently mapped to one of the two interrupt output pin.(FIFO) buffer can be used to store data, which will processor load Minimize and reduce overall system consumption.Low mode supports intelligent management based on movement, leading to very low consumption sensing movement and Acceleration measurements.ADXL345 3 mmx5 mmx1 mm,14 pin small thinName: ADXL345 modules ( three - axis acceleration ): -291Chip: ADXL345 supply: 3-5VMeans of communication: IIC/SPI communication protocolMeasuring range: +/- 2G +/- 16GColour: BlueMaterial: Plastic + MetalPackage Contents:10 x modules10 x pin headersOnly the above package content, other products are not included.Note: Light and different displays may the color of the item in the a little different from the real thing.
