Design and development of multi-purpose controller to measure and control moisture, temperature, and time for crop processing

The microcontroller served as the brain and central processing unit of the controller. The project served as multipurpose controller to the machine for crop processing. It focused on three parameters: moisture, temperature, and processing time. The operators can also use this controller to measure the initial moisture and temperature of the crop processing machine. The operator can set the parameters on their own preferences for the machine. An example would be for the crop dryer wherein the operator can set both the final temperature and processing time as the base parameters to turn off the machine or in other option which the final moisture content or humidity can be set to turn-off the machine. This design can be used in three machines simultaneously, and since the operators input the value of the parameters, it can also be used in appliances.
