Internet of Things (IoT) Practice Exam

What limits the types of objects that can become intelligent sensors in IoT?

1. Cost of manufacturing sensors

2. Physical size and power requirements

3. Functionality and integration capabilities

4. Range of wireless communication technology

The correct answer is: Physical size and power requirements

The limitations regarding which objects can become intelligent sensors in the Internet of Things (IoT) largely stem from their physical size and power requirements. Intelligent sensors typically need to be small enough to fit into various devices or environments without being obtrusive. This means that the design and engineering of these sensors must accommodate compact and often intricate forms. Moreover, power requirements play a critical role in determining the feasibility of embedding sensors into objects. Many IoT devices rely on battery power or energy harvesting methods, which means that the energy efficiency of the sensor is paramount. If a sensor consumes too much energy, it may not be practical for use in most everyday objects, which may not have easy access to power sources for regular recharging or replacement. While manufacturing cost influences the adoption of certain sensors, it is the combination of size and power that fundamentally limits the types of objects that can accommodate intelligent sensing capabilities. These factors must align with the existing technological constraints and the operational context in which the sensor will be deployed.
