NAME

RPi::SysInfo - Retrieve hardware system information from a Raspberry Pi

DESCRIPTION

Fetch live-time and other system information from a Raspberry Pi.

Most functions will work equally as well on Unix/Linux systems.

SYNOPSIS

    # Object Oriented

    use RPi::SysInfo;

    my $sys = RPi::SysInfo->new;
    say $sys->cpu_percent;
    say $sys->mem_percent;
    say $sys->core_temp;

    # Functional

    use RPi::SysInfo qw(:all);

    say cpu_percent();
    say mem_percent();
    say core_temp();

EXPORT_OK

Functions are not exported by default. You can load them each by name:

    cpu_percent
    mem_percent
    core_temp

...or use the :all tag to bring them all in at once.

FUNCTIONS/METHODS

new

Instantiates and returns a new RPi::SysInfo object.

Takes no parameters.

cpu_percent

Returns the percentage of current CPU usage.

Takes no parameters.

Return: Two decimal floating point number.

mem_percent

Returns the percentage of physical RAM currently in use.

Takes no parameters.

Return: Two decimal floating point number.

core_temp($scale)

Returns the core CPU temperature of the system.

Parameters:

    $scale

Optional, String: By default we return the temperature in Celcius. Simply send in the letter f to get the result returned in Fahrenheit.

Return: Two decimal place floating point number.

PRIVATE FUNCTIONS/METHODS

_format($float)

Formats a float/double value to two decimal places.

Parameters:
