This small library captures CPU temperature on macOS (Apple silicon processors), all values are in degree Celsius. This library is intended to be used server side (not within a browser) and is designed to work on ARM based systems.
This library is a replacement for our old [osx-temperature-sensor][osx-temp-npm-url] package (which was designed to work on intel based machines).
``bash`
$ npm install macos-temperature-sensor
Make sure, that your deno.json has set the following:
`
{
...
"nodeModulesDir": "auto",
...
}
Install the package with
`bash`
$ deno install --allow-scripts=npm:macos-temperature-sensor
$ deno add npm:macos-temperature-sensor
Here a small example how to use this library index.js:
`js
const macosTemp = require('macos-temperature-sensor');v
let temperature = macosTemp.temperature();
console.log('CPU temperature:');
console.log(temperature);
`
Then run it with node index.js
In Deno it would be index.ts:
`js
import macosTemp from 'macos-temperature-sensor';
let temperature = macosTemp.temperature();
console.log('CPU temperature:');
console.log(temperature);
`
Then run it with deno run -A index.ts
#### Sample output:

This library is used by one of my other libraries [systeminformation][systeminformation-github-url], also available via [github][systeminformation-github-url] and [npm][systeminformation-npm-url]
| Function | Comments |
| --------------- | -------- |
| macosTemp.version() | library version (no callback/promise) |
| macosTemp.temperature() | CPU temperature (if sensors is installed) in Celsius |
| - cpu | cpu max temperature |
| - soc | soc avg temperature |
| - gpu | max gpu temperature |
| - cpuDieTemps | array of all cpu die temperature points |
| - probeGroupsTemps | array of all probe groups temperature points |
| - gpuDieTemps | array of all gpu die temperature points |
This library is supposed to only work on macOS, apple silicon processors
I am happy to discuss any comments and suggestions. Please feel free to contact me if you see any possibility of improvement!
