Need help building a device to manipulate low voltage

AI Thread Summary
The discussion centers on building a device to manipulate low voltage inputs below 5V by processing and scaling them to specific outputs. An Analog to Digital Converter (ADC) is suggested as a potential solution, along with integrated circuits that can process temperature probe inputs. Using a microcontroller with a built-in ADC is also recommended for flexibility in handling various input types. Additional details about the project could help refine the advice given. The conversation emphasizes the importance of understanding both the input and desired output for effective design.

Hello, I need some assistance building a device. I want to input a voltage below 5v, process it and manipulate it by a programmed amount. It won't be perfectly even so I can't do it by a set resistance, meaning the scaling will be different. Example: input 3.74v process it as 73 degrees, then reference the programmed scale for 73 degrees which would be 2.41v... I am mechanically and electrically inclined, have always been interested in building electronics cause I haven't ever donne it! Any input is appreciated!

Welcome to PF!

Sounds like what you are looking for is an ADC (Analog to Digital Converter). There are also IC's that take a temperature probe as an input and output the result using various protocols. You might also consider simply using a uController with a built-in ADC and simply connecting a temperature probe to it.

A bit more detail on your actual project//goal might help refine answers.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
