Sensors
Sensor science and technology is growing rapidly in response to an ever-increasing demand for faster, cheaper, smaller, and more sensitive means to monitor the world around us. Today’s smartphones are populated with an outstanding array of sensors, which most people are never aware of—allowing our phones to follow our commands and function seamlessly.

• Visual (large pixel count camera)
• Accelerometers for exercise/health measurement and games
• For cellular and Wi-Fi signal strength
• Temperature measurement for local temp
• Touch screen for commands
• Global positioning for maps and traffic functions
• Voltage and current measurement for battery utilization optimization
• Light (auto screen brightness adjustment)
• Sound (2 mics – background noise and voice)
• Speakers for phone, games and music
