What is Arduino®
Arduino® is an open-source prototyping platform based on easy-to-use hardware and software. Arduino® boards are able to read inputs – a light-on sensor, a finger on a button or a Twitter message – and turn it into an output – activating of a motor, turning on an LED, and publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming language (based on Wiring) and the Arduino® software IDE (based on Processing). Additional shields/modules/components are required for reading a Twitter message or publishing online. Surf to www.arduino.cc for more information.
Product Overview
The MMA8452Q accelerometer module is a smart, low-power, three-axis, capacitive MEMS accelerometer with 12 bits of resolution. It is packed with embedded functions with flexible user-programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data. It has user-selectable full scales of ± 2 g/± 4 g/± 8 g with high-pass filtered data, as well as non-filtered data available in real-time.
Specifications
- supply voltage: 1.95-3.6 V
- interface voltage: 1.6-3.6 V
- current consumption: 6-165 μA
- ± 2 g/± 4 g/± 8 g dynamically selectable full-scale
- output data rates (ODR): 1.56-800 Hz
- 12-bit and 8-bit digital output
- I²C digital output interface (operates to 2.25 MHz with 4.7 kΩ pullup)
- two programmable interrupt pins for six interrupt sources
- three embedded channels of motion detection
- orientation (portrait/landscape) detection with set hysteresis
- high-pass filter data available in real-time
Pin Layout
| 3.3V | Power output – 3.3 V output. |
|---|---|
| Vcc | Power supply – It should be between 3 and 5 V. |
| SDA | I²C data signal – Bi-directional data line. Voltage should not exceed the |
power supply.
SCL| I²C clock signal – Master-controlled clock signal. Voltage should not
exceed the power supply.
SA0| I²C address – I2C least significant bit of the device I2C address.
I2| Interrupt 2 – Programmable interrupt. Can indicate data ready, orientation
change, tap, and more.
I1| Interrupt 1 – Programmable interrupt. Can indicate data ready, orientation
change, tap, and more.
GND| Ground – 0 V/common voltage.
