Does anyone know what Biyou is for? Thank you very much for knowing the trouble and helping to solve it! Wait for the answer online, hurry!

Dear subject, hello, I just helped you search online for a long time and found the following information: Biyou Sensor Technology and Biyou Sensor Network are both owned by this company. Biyou Sensor Network has more information about this company, and I understand that Biyou Sensor Network is a new comprehensive website platform of this company. According to their website introduction, their platform is the first comprehensive platform in the field of sensors in China, which mainly provides online purchase inquiries and product technical information of excellent high-end brand sensors at home and abroad. In addition, I learned that Li, the founder of Biyou Sensor Network (Biyou Sensor Technology), also has a company called Shenzhen Science and Technology Co., Ltd., which was established in 2009 and is also a related company in the sensor field. I know that at present, I hope to help the subject! In addition, I would like to ask the subject what these are for? I hope the subject can adopt my answer and say thank you again!
