GY-291 ADXL345 Accelerometer Module

Description

GY-291 ADXL345 Accelerometer Module The ADXL345 is a small, low power, complete 3-axis MEMS accelerometer modules with both I2C and SPI interfaces. The ADXL345 board feature on-board 3.3V voltage regulator and level shifter, which makes it simple to interface with 5V microcontrollers such as the Arduino. GY-291 Pin Configuration Pin Name Pin Configuration GND Ground Pin VCC Power Supply pin (3V to 6V) CS Chip Select Pin INT1 Interrupt 1 Output INT2 Interrupt 2 Output SDO Serial Data Output SDA Serial Data Input & Output SDL Serial Communication Clock Features | Specifications: 3V-6V DC Supply Voltage On-board LDO Voltage regulator Built-in Voltage level convertor (MOSFET based) It can be interface with 3.3V or 5V Microcontroller. Ultra-Low Power: 40uA in measurement mode, 0.1uA in standby@ 2.5V Tap/Double Tap Detection Free-Fall Detection SPI and I2C interfaces Measuring Range: ±16g Measuring Values (-16g to +16g): X: -235 to +270 Y: -240 to +260 Z: -240 to +270 How to Use the ADXL345 Accelerometer Module ADXL345 Accelerometer module consists of 8 pins. Using the ADXL345 module with a microcontroller is very easy. Connect VCC and GND pins to 5V and GND pins of Microcontroller. Also, connect SCL and SDA pins to the SCL and SDA pins of Arduino. The basic structure of the accelerometer consists of fixed plates and moving plates. When the acceleration is applied on an axis capacitance between fixed plates and moving plates is changed. This results in a sensor output voltage amplitude, which is proportional to the acceleration. Applications of ADXL345 Accelerometer Cost-sensitive, low power, motion- and tilt-sensing applications Mobile devices Gaming systems Disk drive protection Image stabilization Sports and health devices Package Includes: 1x GY-291 ADXL345 Module Documents: Instructions Datasheet Related Products: SENSORS | MODULES
