Applications of MMA8452QT
• E-compass applications
• Static orientation detection (portrait/landscape, up/down,
left/right, back/front position identification)
• Notebook, e-reader, and laptop tumble and freefall detection
• Real-time orientation detection (virtual reality and gaming 3D
user position feedback)
• Real-time activity analysis (pedometer step counting, freefall
drop detection for HDD, dead-reckoning GPS backup)
• Motion detection for portable product power saving (auto-sleep
and auto-wake for cell phone, PDA, GPS, gaming)
• Shock and vibration monitoring (mechatronic compensation,
shipping and warranty usage logging)
• User interface (menu scrolling by orientation change, pulse
detection for button replacement)
