RF module environment refers to the various external conditions and factors that affect the performance and reliability of these modules.

Graphene sensors have the characteristics of small size, large surface area, висока чутливість, Швидкий час реагування, easy fixation of proteins and maintaining their activity, fast electron transfer speed, and can effectively reduce the impact of surface contamination, making graphene sensors show excellent performance in the fields of electrochemical sensing, photoelectric sensing, gas sensing and flexible sensing.

Pressure sensors play an important role as key components in monitoring and controlling pressure changes in modern industrial, automotive, medical and consumer electronics applications. Однак, due to the complexity and variability of the operating environment, pressure sensors may encounter various failures during use, which may affect their performance and reliability.

Система моніторингу тиску в шинах (TPMS) є електронною системою для моніторингу тиску в шинах та температурі в транспортних засобах для поліпшення безпеки водіння та економії палива. Датчики датчиків тиску в шинах є основними компонентами системи TPMS і безпосередньо відповідають за зйомку даних фізичного стану шин та бездротово передавати його в систему управління транспортним засобом. The TPMS system processes the data provided by the sensor and sends timely alarms or alerts to the driver to avoid safety accidents caused by abnormal tire pressure.

Pressure sensors are the most important technical component of blood pressure watches. Their application not only realizes convenient blood pressure measurement, but also provides intelligent solutions for health management. With high precision sensors and advanced algorithms, blood pressure watches can provide accurate real-time data and health trend analysis to help users better manage their personal health.

The accuracy level of a pressure sensor is usually classified according to its margin of error. The different accuracy levels represent the amount of error in the measurement process of the sensor. Common accuracy classes include C3, C2, C1, G1, G2, G3 and G5. Серед них, C3 has the highest accuracy, with an error range within ±0.020%, i.e., 2 parts per million accuracy; while G5 has the lowest accuracy, with an error range within ±0.5%, i.e., 5 parts per thousand accuracy.

To test a pressure sensor, it is necessary to look at its appearance, pressure response, zero point, circuitry and electrical performance. By comprehensively analyzing and judging the test results, the performance and condition of the sensor can be accurately assessed and provide strong support for subsequent maintenance and use.

Different types of air pressure sensors have significant differences in accuracy. Gauge pressure sensors are suitable for general applications, absolute pressure sensors provide high accuracy, and differential pressure sensors are used for flow and filtration monitoring. Choosing the right sensor requires considering accuracy requirements, Сценарії застосування, environmental factors, and cost.

Gauge pressure sensor is a sensor that measures the relative pressure, тобто. значення тиску відносно атмосферного тиску. A differential pressure sensor is a sensor that measures the pressure difference between two measurement chambers. An absolute pressure transducer is a transducer that measures pressure relative to vacuum or absolute zero.

Submersible pump pressure sensors operate on the principle of electrical signal changes due to pressure changes. Типово, the pressure sensor contains a pressure sensitive element, when the external water pressure acts on the element, it will cause its deformation, which in turn changes the internal resistance or capacitance. This change is converted into an electrical signal, which is processed by a circuit that outputs a signal proportional to the water pressure. The submersible pump reads this signal to adjust its operating status, such as starting, stopping, or regulating the pump speed to adapt to different water depth conditions.
