I am trying to design this any ideas?



A new COVID-19 “fictional” vaccine will be available at the end of April 2021. The vaccine MUST BE stored between -20˚C and 10˚C. You are tasked with designing, simulating, and breadboarding a storage temperature monitoring device that will produce an alarm if the temperature exceeds the storage temperature range. It has also been requested to add a “test” feature that the user has available which verifies the operation of the device. The following components MUST BE included as a functional portion of the design, meaning that each part contributes to the functionality of the final design:

1. Must include at least two of following (they can be two of the same component):

a. LM741

b. AD712

c. Diode (any type)

d. BJT Transistor

e. MOSFET Transistor

2. NTCLE100E3101GB0 (THERMISTOR NTC 100OHM 3560K BEAD).

NOTE: You will NOT actually use the component. This component can be simulated using a variety of methods. DO NOT go out and purchase the thermistor. It is not necessary!

 

What ideas do you have?

 

I was thinking And think this could work out fine, but it its not working as I pictured it, i am reaching my limits
and plus I couldn't incorporate all the elements required.

 

Your LED is backwards.
Also it should be placed on the collector side of the transistor.

okay, I will fix that. But Is there any better way to do the whole circuit over all, following the Specifications?

It looks that you do not care of have it working but to be told the whole circuit.
