Introduction

  • MMA8452 module, high precision tilt sensor module

  • Module type: GY-45-52

  • Power supply: 3-5v (Communication fully compatible with 5V operating system)

  • Module size length * width =14.5mm * 20.5 mm

  • Mounting hole diameter 3mm, hole distance 15mm

  • 51 test code

  • MMA8452Q is a 12 bit resolution of intelligent low power, three axis, capacitive micromachined acceleration sensor. The acceleration sensor is rich in embedded features, with a flexible user programmable option, you can configure up to two interrupt pins. Embedded interrupt function can save the overall power consumption, and the burden of the main processor can be relieved. MMA8452Q

  • The user selectable range of + 2g/ + 4g/ + 8g can be real-time output of high pass filtering data and non filtering data. The device can be configured to generate an inertial wake-up interrupt signal which can be configured with any combination of arbitrary combination, which makes the MMA8452Q to maintain a low power mode at the same time in the stationary state.

Feature

  • Supply voltage: 1.95 V to 3.6 V

  • Interface voltage: 1.6 V to 3.6 V

  • 4g/ + 8g + 2g/ dynamic range

  • Output data rate (ODR) range: 1.56 Hz to 800 Hz

  • Noise: 99 g/ V Hz

  • 12 bit and 8 bit digital output

  • I2C digital output interface (the maximum frequency of 4.7 K at the time of the pull up resistor is 2.25 MHz)

  • 2 programmable interrupt pins for 6 interrupt sources

  • 3 motion detection embedded channels

  • Free fall or motion detection: 1 channel

  • Pulse detection: 1 channels

  • Shaking test: 1 channels

  • Direction (transverse / longitudinal) detection with setting lag compensation

  • Automatic wake up and automatic sleep ODR can be automatically changed

  • High pass filtering data can be real-time output

  • Self detection

  • Comply with RoHS standards

  • Power consumption: 6 A - 165 A

Typical application

  • Electronic compass application

  • Detection of static direction (horizontal / vertical, upper / lower, left / right, front / rear position identification)

  • Laptop, e-book reader and portable computer to fall and fall detection

  • Real-time direction detection (virtual reality and game machine 3D user position feedback)

  • Real-time activity analysis (step count, free fall detection, HDD GPS backup) for the navigation

  • Application of portable energy saving product detection (for mobile phones, GPS, PDA, game machine automatic sleep and Automatic wake-up)

  • Impact and vibration testing (mechanical and electrical integration compensation, shipping and warranty use records)

  • User interface (by way of changing the implementation of the menu scroll, for the button to replace the label detection)
