The reliability and precision of sensors have important impacts on their applications in many aspects, including the following points:
Impacts of reliability:
System stability: If the sensor is not reliable, it is prone to malfunctions or false alarms, which can lead to instability of the entire application system and may even trigger safety issues, such as in industrial automation or automotive electronics and other fields.
Maintenance cost: Frequent failures require frequent repair or replacement of sensors, increasing the maintenance cost and time investment.
Data continuity: An unreliable sensor may result in discontinuous data collection, affecting the accurate assessment and analysis of the system state.
Impacts of precision:
Decision accuracy: In occasions that require accurate measurement, such as in medical diagnosis and scientific research, insufficient precision will lead to incorrect decisions and conclusions.
Control effect: In the field of automatic control, such as in precision machining or environmental control, a sensor with low precision will make the control effect poor and difficult to achieve the expected quality or performance standards.
Resource utilization efficiency: For some resource management applications, such as energy monitoring, insufficient precision may lead to unreasonable resource allocation and affect the efficiency of resource utilization.
Product quality: In the manufacturing industry, the precision of sensors directly affects the quality and consistency of products.
For example, in the aerospace field, the reliability and precision of sensors are of crucial importance. An unreliable altitude sensor may lead to a flight accident, while a pressure sensor with insufficient precision may affect the precise control of the flight attitude. In smart home, the reliability of the temperature sensor affects the normal operation of the air conditioning system, and insufficient precision may lead to inaccurate indoor temperature regulation and affect the user experience.
