    Most of the sensors have analog output so you will require an ADC to convert the analog voltage into digital
    there can be two kinds of DAS
    1. Online Tracking i.e. the data to be monitored is directly sent to the final recording device eg. PC
    2. Offline Tracking i.e. the data to be monitored is stored temporarily in the memory & later on it is connected to the PC where the whole log is copied.
    The parameters are monitored on real time basis
    In Online tracking you wont require memory or RTC or memory for recording as the PC is used, in offline tracking you will require an RTC, EEPROM (for temporary storage)
    now wot kind of DAS are you planning to do? 😒

    Hey amol..... thak u very much.....
    Tell me if i giv temp,pressure flow...etc as a input signals to d multiplexer,after converting dem into electrical signal, will it work????

    Is the following sequence correct???

    i/p signal-transducer-signal conditioning block- a/d converter- microcontroller- interfacing-display...

    why do u require a d multiplexer? just use a higher channel ADC like ADC 0808 8 channel, 8 bit ADC check this Link for ADC 0808 interfacing <a href="https://www.dnatechindia.com/index.php/Tutorials/8051-Tutorial/Interfacing-ADC0808-To-8051.html" target="_blank" rel="nofollow noopener noreferrer">Best Online Shop for Electronic Components in India</a>or if you need higher bit ADC then use the MCP 3210/02/04/08 which is a 12 bit ADC and the last two digits represents the number of channels

    yes the sequence is correct

    In an EFI project of car engine(we used 1sz Toyota Vitz engine) we selected Motorola 68HC11 micro-controller in early project phase. Good thing is this MCU has built-in ADC which i guess maybe present in other micro-controllers too. So it ll be better to use those MCUs with built in ADC.
    For learners, 8051 is better...
