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, alta sensibilidade, Tempo de resposta rápido, 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.

Os sensores de pressão desempenham um papel importante como componentes -chave no monitoramento e controle de mudanças de pressão na industrial moderna, Automotivo, Aplicações de eletrônicos médicos e de consumo. No entanto, 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.

Tire Pressure Monitoring System (TPMS) is an electronic system for real-time monitoring of tire pressure and temperature in vehicles to improve driving safety and fuel economy. Tire pressure gauge sensors are the core components of the TPMS system and are directly responsible for capturing the physical condition data of the tires and transmitting it wirelessly to the vehicle control system. 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. Entre eles, C3 has the highest accuracy, with an error range within ±0.020%, Ou seja,, 2 parts per million accuracy; while G5 has the lowest accuracy, with an error range within ±0.5%, Ou seja,, 5 parts per thousand accuracy.

Para testar um sensor de pressão, é necessário olhar para sua aparência, resposta de pressão, ponto zero, circuito e desempenho elétrico. Analisando e julgando de forma abrangente os resultados do teste, 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, application scenarios, environmental factors, and cost.

Gauge pressure sensor is a sensor that measures the relative pressure, i.e. the pressure value relative to atmospheric pressure. 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. Typically, 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.
