The system uses 3 sensor : Temperature sensor, humidity sensor and IR sensor for rainfall measurement. These 3 sensors will measure the physical quantity and the signal from 3 sensor will be converted to digital signal using ADC 0804.
End of January 2012, I have finished the hardware part involving 3 sensors and ADC. I'll explain about the hardware part in next post.
By now, I am busy with the software part to do a programming using verilog HDL.
