Consumer MEMS Sensors (Accelerometers, Gyroscopes, Environmental)

Microelectromechanical system (MEMS) sensors for smartphones, wearables, earbuds, and IoT devices: 3-axis accelerometers (screen rotation, step counting), gyroscopes (navigation, image stabilization), barometric pressure sensors (weather, altitude), and environmental sensors (humidity, temperature, gas). Bosch Sensortec, STMicroelectronics, and TDK InvenSense dominate the smartphone MEMS market. Bosch Sensortec ships approximately 4 billion MEMS sensors per year and is embedded in nearly every major Android OEM. A single Bosch BMA280 accelerometer costs ~$0.30 but is in 100M+ phones annually.
