Problems solved by technology

Although China has achieved great development in recent years, due to the influence of product design technology and detection technology, domestic sensors are still at a low-end level and need further improvement and development

As far as sensor detection is concerned, the detection of these types of sensors in China is still at a relatively elementary level. They mainly use oscilloscopes and simple test tooling for product detection, which has the disadvantage of not being able to conduct comprehensive and systematic detection of the output performance of the product. The disadvantages of undetectable part of the performance are not only inconvenient and inefficient, but also the test results are greatly affected by the subjective factors of the operator, the controllability of the product is poor, and the stability and reliability of the product cannot be guaranteed.
