The Department of Electrical Engineering was established under College of Agricultural Engineering with the objective of offering courses in the discipline of Electrical and Electronics to the students of Agricultural Engineering and cater to the needs of research in the area of Electrical and Instrumentation Engineering. Later in the year 1972, M.Tech. programme in Electrical Engineering was started with specialization in Instrumentation Engineering and Systems & Control Engineering. Students were taught certain aspects of Electrical, Electronics and Computer Engineering applicable to Agricultural Engineering which they can directly or indirectly apply in their respective fields after graduating. With the emergence of computer discipline, the department was renamed as Department of Computer Science and Electrical Engineering (CSEE) in 1991 and M.Tech. programme in Computer Science and Engineering was started in 1999. Two university level service units namely Instrumentation Cell and Computer Center established under the control of Dean, COAE&T were looked after by the departmental faculty.

The Department of Computer Science and Electrical Engineering played a significant role in designing, planning, procurement and deployment of campus wide optical fiber/wired network to provide data connectivity which provides the campus wide internet and video conferencing facility to faculty, staff and students of the university. The smooth and effective working of this network is coordinated by the department. The management, operation and maintenance of PAU telephone exchange (EPABX) are also looked after by the department. Master of Computer Applications program was started in the year 2009 after renaming Computer Center as School of Information Technology (SIT). The Department of Computer Science & Electrical Engineering and School of Information Technology were merged and renamed as School of Electrical Engineering and Information Technology (SEEIT). It was rechristened as Department of Electrical Engineering and Information Technology (DEEIT) in 2018.

Presently, DEEIT is engaged in offering courses to the undergraduate students of all colleges of the university and postgraduate students of the College of Agricultural Engineering & Technology. The department also offers programmes in M.Tech. (Computer Science & Engineering) and Master of Computer Applications. The primary objective of the department is academics and research in allied agricultural fields in collaboration with other departments by development and hosting of different softwares, portals, decision support systems, mobile applications, etc. Other mandate is to provide basic IT services to the university including email and information communication for data, voice & video through University Data Centre. Wi-Fi connectivity and internet facilities are provided to all hostels and buildings in the campus. The website of the university (www.pau.edu) is also maintained by the data centre. Maintenance of web server and remote access server is also under the purview of data centre. The department has been imparting computer education to faculty, staff and students of the university about the use of ICT tools. The department has been adjudged the best emerging institute of CS & IT by RDS Media, New Delhi.
