SENSOR 0-5V, 4-20mA, 0-24V + ELECTRON

General
1

1.- I have seen many analog sensors but for arduino from 0 to 5V
Is it there any efficient method to reduce in a linear way to 0 - 3.3V?

2.- I have seen many analog industrial sensors but for 4-20mA
Is it there any efficient method to reduce in a linear way to 0 - 3.3V?

3.- I have seen many analog industrial sensors but for 0-24V
Is it there any efficient method to reduce in a linear way to 0 - 3.3V?

Please some diagram

for 4-20 mA:

From a higher voltage to a lower voltage use a voltage devider:

Plenty of examples on the internet!

Hi Aart,

Can you provide a link with some more background knowledge of the 4-20mA solution? I am not able to find the right search tags.

A lot of industrial sensors like pressure sensors, thermocouples,flow meters, distance sensors come with these analog outputs. There are products with will takes these 0-5V,0-10V,0-24V or 4-20mA signal and convert into digital values which can be interpreted by the electron and can be converted in real world values.

  1. 0-5V,0-10V You can try this board
    16bit 0-10V ADC
  2. 4-20mA you can use this one
    4-20mA current receiver
  3. 0-24V ADC
    0-24V ADC

Thanks
