public interface Sensors

Sensors include hardware sensors to monitor temperature, fan speed, and other information.

Drivers may or may not exist to collect this data depending on the installed hardware and Operating System. In addition, software-hardware communication may suffer intermittent errors when attempting to access this information. Users should expect, test for, and handle zero values and/or empty arrays which will result if the OS is unable to provide the information.

Windows information is retrieved via Windows Management Instrumentation (WMI). Unfortunately, most hardware providers do not publish values to WMI. If a value is not available through the Microsoft API, Oshi will attempt to retrieve values as published to WMI by Open Hardware Monitor if it is running.

Method Summary

Modifier and Type	Method and Description
double	getCpuTemperature() CPU Temperature
double	getCpuVoltage() CPU Voltage
int[]	getFanSpeeds() Fan speeds

Method Detail

getCpuTemperature

double getCpuTemperature()

CPU Temperature

Returns:

CPU Temperature in degrees Celsius if available, 0 otherwise.

getFanSpeeds

int[] getFanSpeeds()

Fan speeds

Returns:

Speed in rpm for all fans. May return empty array if no fans detected or 0 fan speed if unable to measure fan speed.

getCpuVoltage

double getCpuVoltage()

CPU Voltage

Returns:

CPU Voltage in Volts if available, 0 otherwise.
