Did anyone here learn the Visual Basic before? If you did, then this data acquisition system would be a piece of cake to you!
Ok, the main goal of this project is to use a PC to connect the homemade data acquisition hardware and produce the GUI for user-friendly graphical presentation. So, in this project, the important thing is using a PC for GUI display.
The circuit is being built based on the ATmega8, where the chip has the on chip 10-bit resolution A/D Converter. You must make sure that you’ve fully connected the LM335 temperature sensors to the six channels ADC input. The reasons why LM335 temperature sensors are used because it can measure the temperature using two wires remotely! In this case, you’re having the choice to connect up to eight sensors with the ATmega8 TQFP package.
Normally, by sending a serial of common from PC, you’ll be able to capture the analog inputs. In other hands, the readings will be displayed, either in graphically or text data format. In addition, you’re allow to record the data as the database and keep a track on it as well!
