This project use a PC for GUI display and AVR Based data converter board. The circuit is built with the ATmega8. The GUI programming with Visual Basic to receive data from ATMega8 vai RS232. The ATMega8 chip has the onchip 10-bit resolution A/D Converter. Temperature sensor are connected to the 6 channels ADC input. You can connect up to 8 sensors with the ATmega8 TQFP package.
