Fremont, CA: Over the last few decades, the construction industry has prioritized energy efficiency, water conservation, and clean power. Many building owners understand the advantages of LED lighting and high-efficiency motors, among other technologies. On the other hand, buildings can use resources even more efficiently if a smart platform controls MEP systems. This opens up a plethora of possibilities for the Internet of Things (IoT).
Traditionally, building systems such as lighting, air conditioning, and space heating were controlled manually. Nevertheless, the needs of a building and its occupants change all the time, making it impractical to adjust manual controls all the time. Building systems must measure operating conditions and adjust themselves to achieve peak performance. This is only possible by incorporating sensors, which play an important role in smart building systems.

Choosing the Right Sensor for Each Application
There are many different types of sensors, and their prices vary greatly depending on the application. The following are two critical factors to consider when selecting sensors:
• The variables that must be tracked.
• The required precision and accuracy.
Several sensors will frequently measure the same variable using different methods, and selecting the best match for each application is critical. Some sensors are also susceptible to environmental factors, which may limit their use in specific applications.
Consider occupancy sensors used to control lighting fixtures and can be infrared, ultrasonic, or dual. Infrared sensors require a clear line of sight between themselves and the occupants, whereas ultrasonic sensors can detect occupants hidden behind obstacles. When ultrasonic sensors are close to sources of noise or vibration, they may operate incorrectly.
When multiple sensing methods are available for the same variable, cost and accuracy differences are expected. The sensor should ideally have adequate accuracy for the intended application, but excessive accuracy will be a waste of money. Typically, the most precise sensing methods are also the most expensive.
Combining Sensors with Enhanced Reality Systems
The combination of sensors and Building Information Modeling (BIM) opens up a plethora of opportunities. BIM models, for example, can be automatically updated with information collected by sensors. This allows maintenance personnel to more easily monitor difficult-to-reach equipment and components. Engineers and other technical personnel can also use headgear to visualize important data during a site inspection.
When working with variables that are undetectable by humans, enhanced reality comes in handy. For example, headgear and sensor data can be used to "see" temperature differences, airflows, electric current, water flow inside piping, and so on. This feature simplifies troubleshooting and inspections while also improving workplace safety. When hazards such as high temperatures are made more visible through enhanced reality, they can be avoided more easily.
