Dorhea 5PCS ADXL345 Digital Inclination Sensor Acceleration Module Digital Tilt Angle Sensor Gravity 3-Axis AVR ARM MCU for Ardu ino
Ultralow power: as low as 23 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V (typical) Power consumption scales automatically with bandwidth Fixed 10-bit resolution Full resolution, where resolution increases with g range, up to 13-bit resolution at ±16 g (maintaining 4 mg/LSB scale factor in all g ranges) Module supply voltage range: 4.0 V to 6 V I/O voltage range: 1.7 V to 3.6V SPI (3- and 4-wire) and I2 C digital interfaces Flexible interrupt modes mappable to either interrupt pin Measurement ranges selectable via serial command Bandwidth selectable via serial command Wide temperature range (−40°C to +85°C) 10,000 g shock survival Pb free/RoHS compliant Several special sensing functions are provided: Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Freefall sensing detects if the device is falling. These functions can be mapped individually to either of two interrupt output pins.Pin definition: 5V: 5V power supply 3V3: 3.3V power supply GND: ground Vs: supply voltage CS: chip select SCL: I2C serial clock line/SPI clock terminal SDA: Serial Data (I2C) / Serial Data In (SPI 4-wire) / Serial Data In and Out (SPI 3-wire) S DO: Serial Data Output (SPI 4-wire) / Alternate 12C Address Select (I2C) INT 2: Interrupt 2 pin INT 1: Interrupt 1 pin Instructions for use: Note that the address of the module in 12C mode is determined by the S DO pin Package Included: 5 x ADXL345 Gravity Sensor Acceleration Module
Product Features
- ADXL345, it's a low cost cap-based accelerometer sensor, 3-axis accelerometer with high resolution (13-bit), high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0.
- Digital output data is formatted as 16-bit twos complement, supports I2C/SPI, low power, compact accelerometer.
- The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock.
- Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds.
- individually to either of two interrupt output pins.
