Raspberry Pi - Temperature measurement

Measure the CPU and GPU temperature of a Raspberry Pi in degrees Celsius or Fahrenheit.

Installation

npm install rpi_measure_temp --save

Usage

All methods are promise-based and hence await'able and then'able.

Await

const { measureCPU, measureGPU } = require('rpi_measure_temp');

(async () => {
    console.log('CPU Temp:', await measureCPU())
    console.log('GPU Temp:', await measureGPU())
})()

Then/Catch

const { measureCPU } = require('rpi_measure_temp')

measureCPU().then(result => {
    console.log(result)
    // ...
}).catch(error => {
    console.log(error)
})

Sample output

{ celsius: 42.932, fahrenheit: 109.2776 }

Round result

Use the JavaScript built-in functions to round your results.

measureCPU().then(result => {
    const roundedValue = Math.round(result.celsius) // Rounding to the nearest integer
    const flooredValue = Math.floor(result.celsius) // Rounding down
    const ceiledValue = Math.ceil(result.celsius) // Rounding up
    const decimalValue = result.fahrenheit.toFixed(2) // Rounding to 2 decimal places after comma
})

Note

Since the CPU and GPU of the Raspberry Pi are on one chip, the temperature sensor provides similar values for both chips.
