Microcontroller with RTD Temperature Sensor and Data Logging

[NY]

Hello Everyone,

I am working on a prototype development for temperature controll and data logging. Could someone help with which board I should procceed. should I select a board and add shields like in arduino or is it possible to buy a board with ethernet and modules for RTD sensors (PT100).

Our rough functional requiremnt is described below:

Functional Requirements

Sense Temperature T1

Sense Temperature T2

Sense Temperature T3

Using an algorithm to controll the following:

Control Voltage to Peltier (max 30V)

Control Current  to Peltier (max 10 A)

LCD Display functions

Set Target Temperature

Show measured data as numeric values and graph

Set names for sensors (optional)

Set save frequency (save every xx seconds)

Data Logging:

Save sensor values as .csv Files (either through Ethernet  on to a web server or on a SD card)

T1, T2, T3, Voltage to Peltier, Current to Peltier

Looking at your requirements, you could use any PSoC-62 eval boards. With this, you will be able to achieve SD card interface & LCD interface. The temperature sensors need to be connected to the ADC's with some signal conditioning done according to the application needs and the Peltier control loop can be implemented on the m4 core. You could use the below link to select your PSoC device by using filters and then select the available eval board:

We also have code examples to interface with SD card and other peripherals. Please find the link below for the examples:

Hi Ram,

Thank you for the response. Is it also possible to add ethernet module? so that we can configue the peltier control parameters thorugh the an IP?

it would be very helpful if we could get some support to get this off the ground.

Thank you.

Do you want to connect an external ethernet module to the board and get the functionality? If so, can you please mention the ethernet module part number. Also, have you previously used this module with any controller?
