CPU Monitor Jr.

CPU Monitor Jr. is an open source project for monitoring the performance of a Windows computer using a WiFi connected ESP32 board and TFT display.

It uses of two platforms. The first is Windows, with a Windows service gathering and sharing the computer's performance data.  The second is an ESP32, displaying that data on a TFT display.

Below is an example of two (ESP32) LilyGo T-Display S3 devices each monitoring a separate computer at the same time.  Displayed are the names and LAN IP addresses of each computer, as well as, their CPU temperature, memory percentage used, historical total and current core loads. The top device is monitoring a four core Windows computer, the bottom device is monitoring a 24 (48 virtual) core Windows computer.

TFT Display

Monitoring begins as soon as the computer is turned on.

To get the CPU temperature CPU Monitor Jr.'s Windows service uses either Open Hardware Monitor or Core Temp.  If Core Temp is used, the Core Temp program must also be running. This is explained in more detail, along with other aspects of the project, in the following video:

As for the hardware ...

Below are the affiliated links for the components used to put this project together:

Version 2:

  LILYGO T-Display S3   

Version 1.1 (designed for an LCD display):

   ESP32 DOIT Devkit v1
    1602 LCD with I2C module  (please ensure that the LCD monitor with the IC2 module is selected)  
   DS3231 RTC with AT24C32 IIC module  

Here too are some 3D printable cases I designed for the two versions:
