raspberry pi – Multiplexing PT with CD – Electrical Engineering Stack Exchange

Please correct me if i’m wrong in this. Since it expands i cant post it as a comment.

But you can read and write to the pins quite fast. I could order online but it would take weeks and cost a lot import duties to india. The remaining circuit consists of routing each of this 1mA to each pt I will hand pick the resistors but what about temperature compensation? For more info pleae look at this Forum Post. Board Setup and Configuration. The playground is a publicly-editable wiki about Arduino.

Here is the plan: Futhermore, the is able to work with analog values; in the case of the Arduino, you are able to use the analog inputs with a voltage between V and route them to an Analog-In Pin on your Arduino. If some other idea could be evolved, it would be great!


Futhermore, the is able to work with analog values; in the case of the Arduino, you are able to use the analog inputs with a voltage between V and route them to an Eatasheet Pin on your Arduino. Related Hardware and Initiatives. I dont know if i should change the edit figure and text or keep it like this. It may affect the actual current. Sign up or log in Sign up using Google. Now my problems are: There is no such limit on switch current- 1uA is leakage.

Of course, there is no way to measure the resistance of the other two leads because no significant current passes through them. Each of these pins have to be connected to one digital out pin on the Arduino. As i have read in distributed posts here as well as in some papers eg.


I am guessing this should work: I will take Sephro’s suggestion of HC The multiplexers would then be switched to the same input at the same time. Sign up using Email and Password. Realistic problems are going to crop up when you attempt to protect the inputs against the things that can happen off board. Board Setup and Configuration.

I did not think about voltage compliance with A0. Kindly let me know if there are any mistakes or improvements in the above scheme. If you really want to measure ‘top’ lead resistance for some reason other than break protection for which A0 suffices you can add another analog multiplexer and pick off the voltage at the ‘top’ of the RTD. In my edit, i made a mistake. I am a novice mechanical eng. Bimpelrekkie One current source for each pt is a good idea, thanks.
