I2C stands for an integer-integrated circuit. This is a commonly used communication protocol that is flexible enough to be used for a wide variety of applications. Specifically, I2C is a serial communication method with bi-directional two-wire communication. Any sensors and secondary devices only communicate when asked to by the primary.

Data centers exist all over the world, whether they are dedicated buildings or sections of buildings, and each houses computer servers. In the United States alone there are around 3 million data centers. Out of these 3 million, approximately 3,000 are large data centers while the rest are smaller server rooms in businesses.

Pressure transducers all have some degree of variation in output caused by changes in temperature. The best way to compensate for such variation is to employ components on the PCBA that respond to temperature. These components can be fixed in value, adjustable like a potentiometer, or feed into a digital circuit.

A variety of pressure sensor designs are available today. Two of the most common sensor types are MEMS and capacitive sensors.
For referring to variable capacitive sensing technologies, four specific terms are commonly used: pressure transmitters, transducers, sensors, and switches. Capacitance is the detection and measurement of pressure by the change in voltage across a capacitor. The capacitance of sensing technology can be fixed or adjustable and varies dependent on the application. Capacitive sensing technology is highly precise, boasting accuracies of up to ± 0.07% of full scale. This pressure sensing technology is used for applications where a high degree of accuracy is crucial, such as engine test stands and pressure decay leak detection.

Thermal compensation is used to offset sensor performance when efficiency is impacted by fluctuations in temperature. Transducers used for precise testing and measurement applications, such as in engine test stands, undergo thermal compensation. Many transducers used in other critical applications may be thermally compensated. Thermally compensating sensors is crucial as temperature can have a significant impact on performance if not accounted for. This step in manufacturing counteracts the effects from changes in temperature that can influence the accuracy of a transducer's output. Thermal influence the accuracy of a transducer's output. Thermal compensation helps reduce the impact of temperature changes on sensitive components.

In HVAC and refrigeration, pressure sensors monitor pressure changes to indicate when issues arise. Drops in pressure can alert technicians of needed maintenance or larger problems. Within the variety of HVAC applications are also numerous available sensors for every environment. For example, industrial pressure sensors can be used to measure the pressure of fluorocarbon refrigerants, the pressure of chilled water in chiller systems, or the pressure of refrigerant in a refrigeration system.

Today's world depends heavily on the production of ventilators and the safety of critical environments. However, said safety is not dependent on room pressure monitors alone. High accuracy industrial pressure sensors contribute to production efforts for ventilators.
When designing a new system or device, there are enough problems to solve without worrying about the reliability of pressure transducers. Choosing a sensor with a low total error band can make designing the system easier.
