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.

Ngokukhula ngokuthe ngcembe kwetekhnoloji ye-drone ye-R&D, iidrones ziye zatsala ingqalelo kuzo zonke iindlela zobomi ngenxa yenqwelomoya yazo ephantsi, ixabiso eliphantsi, ukuguquguquka okuguquguqukayo, kunye nokuphendula ngokukhawuleza. Zisetyenziswa ngokubanzi kwiindawo ezihlala abantu, ezifana nokukhuselwa kwezityalo zezolimo, ukuhlolwa kwamandla, kunye nokunyanzeliswa kwamapolisa, ukukhangela i-geological prospecting, ukubeka iliso kokusingqongileyo, ukuthintela umlilo wehlathi, ifilimu kunye nokufotowa kwe-TV emoyeni, njl. obufana nobomi bebhetri obunyiniweyo buye bavela ngokuthe ngcembe. Kule meko, iteknoloji ye-chip yokulawula amandla ibe yenye yezinto eziphambili ezichaphazela umgangatho weedrones.

Iibhayisikile zombane, ezikwabizwa ngokuba zii-e-bikes, zinikwa amandla ziibhetri ngokwesiseko seebhayisekile. Idibanisa ukuguquguquka kunye nokukhanya kweebhayisikili kunye neenzuzo zezithuthi zombane ezigcina abasebenzi kunye nokunyamezela okuphezulu, okunokuhlangabezana neemfuno zabantu zokuhamba ezimfutshane. Imfuno yeebhayisekile zombane inyuke kakhulu kule minyaka yakutsha nje. Abasebenzi baseofisini kwizixeko ezininzi basebenzisa iibhayisekile zombane njengesixhobo sokuhamba.

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.

The fuel cell voltage monitor (CVM) is an important part of fuel cell engine system and stack inspection. It has the characteristics of multiple channels, fast response and high voltage measurement accuracy. It can perform real-time analysis of the monitored voltage data group, comprehensive and rapid fault diagnosis, and real-time monitoring, diagnosis, storage and query of the status and performance of the fuel cell stack monolithic, which can ensure the stability and reliability of the fuel cell, and improve the working efficiency of the fuel cell.
