Please help me friends !!!!!I need to make a ATmega circuit design to measure various parameters such as pH/Cond/TDS/ORP and Turbidity. All parameters are pre-converted into voltage through specialised transducer set-ups which give out 100 mV to 1100 mV as minimum and maximum readings. The temerature is also measured and fed in as voltage for compensation purposes.
The ATmega has to just read this parameter voltage and temperature compensation voltage, apply a specific formula and display the result corrected to 2 places of decimals and also give out an analog output (100mV-500mV) corresponding to the displayed value. Please help me with guidelines, so that I can make the gadget within the short stipulated time. The ATmega must also give out a pulsed output for triggering an alarm to notify abnormal conditions.
