    Could anyone help me in designing a circuit with LEDs and Comparators?
    The pressure or the level of the liquid to be indicated on the LEDs which will be mounted on the front panel.

    The pressure sensor works at 24V. This level indication should be irrespective of the MCU or Processor. Independent circuit to always indicate the level of the liquid

    You say pressure OR level. Do you know which one you want?
    You say that level will be independent of the uC. Does this mean other IC's can't be used either?
    You say the pressure sender works on 24 volts. That's DC, right? What is the input pressure range and output signal range?
    What is the uC for?

    The level of the alcohol in the container to be sensed with the help of LEDs and comparators.
    For example say there are 4 LEDs and each LED will indicate the level of liquid in the container. [Say LED 1 = 1/4th LED 2 = ½ LED3 = 3/4th and LED 4 = Full]
    Since this container is equipped inside a housing it can only be refilled using a funnel externally.
    The level sensor works at 24V DC.

    The sensor output is also given to the ADC which is interfaced to the Microcotroller to read the level of the liquid. This will give the exact measurement.

    The approximate level of liquid to be known by mounting the LEDs on the front panel and this is just to keep us notified the level independent of the ADC or the microcontroller.

    Hi Krupas,
    Not sure how to do it, but, alcohol, air, and an electrical sensor for a fuse, can send you and all around for a free ride throw the roof! But then I have no idea or how that sensor is designed, so if it’s safe ignore this. Good luck.
