NAME

RPi::BMP180 - Interface to the BMP180 barometric pressure sensor

SYNOPSIS

    use RPi::BMP180;

    my $base = 300;

    my $bmp = RPi::BMP180($base);

    my $f = $bmp->temp;
    my $c = $bmp->temp('c');
    my $p = $bmp->pressure; # kPa

DESCRIPTION

This module allows you to interface with a BMP180 barometric and temperature sensor.

METHODS

new($pin_base)

Returns a new RPi::BMP180 object.

Parameters:

    $pin_base

Mandatory: Integer, the number at which to start the 'pseudo' GPIO pins for communication to the sensor. Anything above the highest numbered GPIO pin will do. For example, 100 or 200.

temp

Fetches the temperature from the sensor.

Parameters:

    $want

Optional: String. By default, we return Farenheit. To get Celcius, pass in 'c'.

Returns a floating point number.

pressure

Fetches the barometric pressure in kPa.

Takes no parameters, returns a floating point number.
