According to the online inquiry of China Education, the Internet of Things engineering major is a promising major, and the Internet of Things technology is widely used in smart home, intelligent transportation, intelligent medical care, intelligent agriculture and other fields, with great potential for future development. Through upgrading from junior college to undergraduate college, students can learn the Internet of Things technology more deeply, master the latest Internet of Things application and development skills, and improve their professional competitiveness. Secondly, students can improve their comprehensive quality and skill level, cultivate innovative thinking and practical ability, and enhance their professional quality and social competitiveness through the study of upgrading from junior college to undergraduate college. At the same time, upgrading from college to undergraduate can also broaden students' career development channels and increase employment opportunities and career choices. However, not being promoted to undergraduate does not mean that there is no employment development prospect. After junior college, you can take part in the work directly, so that you can quickly accumulate work experience and improve your work ability.
