Temperature Sensor Monitor for Apple Silicon M1

• temp_sensor.m: A modified version of the Objective-C code for iOS sensor by freedomtan;

• monitor.cpp: A naive C++ wrapper for temp_sensor.m output for monitoring temperature in the terminal.

Usage

Compile temp_sensor.m and monitor.cpp individually. Then

./temp_sensor | ./monitor or ./temp_sensor

Only test with my Mac mini with M1. Please check your mac's ioreg -lfx output to make changes in temp_sensor.m if needed.

Here is a similar code in swift for getting sensor values using IOKit (for intel Mac)

For intel Mac, an easier way to get sensor infomation:

sudo powermetrics
