This study provides a project-based learning case study of the design of data acquisition module for the greenhouse system. The project-based learning environment is provided to the final year undergraduate engineering students where the students try to develop a prototype of a greenhouse system equipped with various sensors and actuators. The learning target is to develop a fully functional laboratory prototype of the greenhouse with sensors and actuators and perform data acquisition and data logging operations in the greenhouse. In addition to the development of hardware prototype, the students are encouraged to learn the theory and modeling aspects behind the problem. The result of the project-based learning approach has been encouraging since the students were able to design the working prototype of the greenhouse with basic control functionalities.
