MICROCONTROLLER BASED 4 CHANNEL DAQ SYSTEM (ATMEGA328)

The ATmega328 microcontroller is used in this project to design a data acquisition (DAQ) device that can record data from four separate channels. The system uses an integrated ADC to transform analog signals from sensors into digital data, which is then transmitted to a computer for additional processing or displays on an LCD. The system offers real-time data logging and sample speeds that can be selected by the user. Compact and energy-efficient, the design is appropriate for a range of monitoring applications, including industrial process control and environmental sensing. Accuracy, sampling effectiveness, and channel independence are all evaluated during testing.
