Need help building a device to manipulate low voltage

Click For Summary
SUMMARY

The discussion centers on building a device to manipulate low voltage inputs below 5V, specifically converting these voltages into corresponding temperature readings. The primary recommendation is to utilize an Analog to Digital Converter (ADC) or a microcontroller with an integrated ADC for processing the input voltage. Additionally, temperature probes can be employed to provide accurate readings, which can then be referenced against a programmed scale. Further clarification on the project goals would enhance the specificity of the advice provided.

PREREQUISITES
  • Understanding of Analog to Digital Converters (ADC)
  • Familiarity with microcontrollers and their programming
  • Knowledge of temperature probe integration
  • Basic electronics and circuit design skills
NEXT STEPS
  • Research specific ADC models suitable for low voltage applications
  • Learn programming techniques for microcontrollers with ADC capabilities
  • Explore various temperature probe types and their output protocols
  • Investigate scaling algorithms for voltage to temperature conversion
USEFUL FOR

Electronics enthusiasts, hobbyists building custom devices, and engineers looking to manipulate low voltage signals for temperature measurement and control.

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.
