    I am currently working on a circuit, a sensor to detect a very high temperature, any suggestion as to a good design for a prototype? Thanx

    The temperature should be around 150 deg for the sensor to detect problem it is for an engine performance.

    1. I assume you refer to 150 deg. Celsius. It is correct ?
    2. You're referring to an electric motor or combustion engine?

    If the answer to the first question is yes, then I recommend you turn to "high temperature inductive sensor". Some theory in this regard:

    A selection guide:

    If you think to develop a prototype, then you can fill theoretical knowledge in the direction we expounded above, or pay someone to do it. Price for sensor prototype high temperature is very high and exceeds 100 000 USD. So it takes time and money.

    would it possible for me to use a Thermocouple or a Thermistor sensor to determine an engine temperature?? i need HELP ASAP

    One place to start would be to read the datasheet for the LM35. To read its output (temperature), you need only a voltmeter which you can buy for under $5. It's good only to 150°C max, but perhaps that's enough.

    The short answer to your question is yes. I suggest you go to Mouser and start shopping and reading datasheets.
