# Temperature Sensor Monitor for Apple Silicon M1
|
||||
|
||||
- temp_sensor.m: A modified version of the [code](https://github.com/freedomtan/sensors/blob/master/sensors/sensors.m) for iOS sensor by [freedomtan](https://github.com/freedomtan);
|
||||
|
||||
- monitor.cpp: A c++ wrapper of Objective-C output for monitoring temperature in the terminal.
|
||||
|
||||
## Usage
|
||||
|
||||
`./temp_sensor | ./monitor`
|
||||
|
||||
Only test with my Mac mini with M1. Please check your mac's `ioreg -lfx` output if needed.
|
||||
|
||||
