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 = $bmp->pressure; # kPaDESCRIPTION
This module allows you to interface with a BMP180 barometric and temperature sensor.
METHODS
new($pin_base)
Returns a new RPi::BMP180 object.
Parameters:
$pin_baseMandatory: 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:
$wantOptional: 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.
