Temperature Sensor Monitor for Apple Silicon M1

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

• monitor.py: a wrapper for temp_sensor.m output for monitoring temperature in the terminal.

Usage

Compile temp_sensor.m (by clang -Wall -v temp_sensor.m -framework IOKit -framework Foundation -o temp_sensor, Xcode on M1 mac needed). Then

./temp_sensor | ./monitor.py or ./temp_sensor

Only test with my Macbook air 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
