• Resolution

• Sensitivity

• All of the above

What is the primary function of sensors in IoT?

• To collect live data

• To process data

• To connect to the internet

• To act as a user interface

What is the difference between accuracy and precision?

• Accuracy is the closeness to true value, precision is repeatability
