Sensor AccuracyA key Challenge for IoT Sensing

• Sensors for IoT applications are required

to become ever more accurate:

• Precise rotation for VR and AR

• Precise machine motion or vibration sensing

• Highly accurate barometric reading for

altitude measurement

• High fidelity voice and ambient noise pick-

up for voice recognition & noise cancelling

• Higher accuracy generally means more

power consumption so sensor makers

must innovate to keep within power

budgets
