# Temperature Sensor Monitor for Apple Silicon M1 

- `temp_sensor.m`: A modified version of the Objective-C [code](https://github.com/freedomtan/sensors/blob/master/sensors/sensors.m) for iOS sensor by [freedomtan](https://github.com/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.

## References

For **better names** (e.g. what is `PMU TP3w` ?) for the sensors, please refer to

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`
