Hall current sensor is a sensor that detects current by relying on electromagnetic characteristics. It can indirectly measure the current of current-carrying conductor by measuring the Hall potential, making the non-contact measurement of current possible. Hall current sensors mainly include two types: open-loop and closed-loop. The closed-loop Hall current sensor is also called a zero-flux Hall current sensor.

Dengan kematangan teknologi R&D dron secara beransur-ansur, dron telah menarik perhatian dalam semua lapisan masyarakat untuk penerbangan altitud rendah, kos rendah, kebolehgerakan yang fleksibel dan tindak balas pantas. Ia digunakan secara meluas dalam bidang awam, seperti perlindungan loji pertanian, pemeriksaan kuasa, dan penguatkuasaan polis, pencarian geologi, pemantauan alam sekitar, pencegahan kebakaran hutan, filem dan fotografi udara televisyen, dll. Walau bagaimanapun, dengan perkembangan pesat pasaran UAV, kekangan seperti hayat bateri yang terhad secara beransur-ansur menjadi ketara. Dalam kes ini, teknologi cip pengurusan kuasa telah menjadi salah satu faktor utama yang mempengaruhi kualiti dron.

Electric bicycles, also known as e-bikes, are powered by batteries on the basis of bicycles. It combines the flexibility and lightness of bicycles with the advantages of electric vehicles that saves manpower and has high endurance, which can meet people's needs for short-distance travel. The demand for electric bicycles has increased substantially in recent years. Office workers in many cities use electric bicycles as a tool for commuting.

A smart wearable device is a hardware terminal that combines multimedia, sensing, identification, wireless communication, cloud services and other technologies with daily wear to realize user interaction, life entertainment, health monitoring and other functions. There are smart watches, smart bracelets, smart glasses, smart clothing and so on in our common life. Whether we use smart wearable devices to track steps or record sleep time, we all hope that the devices we use are accurate and reliable. Therefore, in order to ensure the reliability and accuracy of the device, smart wearable devices must be completed strict and comprehensive test before delivery.

Monitor voltan sel bahan bakar (CVM) adalah bahagian penting dalam sistem enjin sel bahan bakar dan pemeriksaan timbunan. Ia mempunyai ciri-ciri pelbagai saluran, tindak balas pantas dan ketepatan pengukuran voltan tinggi. Ia dapat melakukan analisis masa nyata kumpulan data voltan yang dipantau, diagnosis kesalahan komprehensif dan cepat, dan pemantauan, diagnosis, penyimpanan dan pertanyaan masa nyata mengenai status dan prestasi tumpukan sel bahan bakar monolitik, yang dapat memastikan kestabilan dan kebolehpercayaan sel bahan bakar, dan meningkatkan kecekapan kerja sel bahan bakar.
