Based on semiconductor technology, HCVAC vacuum is committed to the research and development of new sensor products, including photoelectric sensor, gene sequencing, molecular antenna, multi sign sensing, fingerprint identification and other products. It can sense the need to be measured by the sensitive element in the thin film sensor. After the analysis and processing of the conversion element, the sensed information will be converted into electrical signal or other forms of information output according to certain rules, and then fed back to people or other controllers to meet the requirements of information transmission, processing, storage, display, recording and control.
