NAME
Device::Chip::HTU21D
- chip driver for HTU21D
SYNOPSIS
use Device::Chip::HTU21D;
my $chip = Device::Chip::HTU21D->new;
$chip->mount( Device::Chip::Adapter::...->new )->get;
printf "Current temperature is is %.2f C\n",
$chip->read_temperature->get;
DESCRIPTION
This Device::Chip subclass provides specific communication to a TE Connectivity HTU21D attached to a computer via an I²C adapter.
The reader is presumed to be familiar with the general operation of this chip; the documentation here will not attempt to explain or define chip-specific concepts or features, only the use of this module to access them.
ACCESSORS
The following methods documented with a trailing call to ->get
return Future instances.
read_config
$config = $chip->read_config->get
Returns a HASH
reference of the contents of the user register.
RES => "12/14" | "11/11" | "10/13" | "8/12"
OTPDISABLE => 0 | 1
HEATER => 0 | 1
ENDOFBATT => 0 | 1
change_config
$chip->change_config( %changes )->get
Writes updates to the user register.
METHODS
read_temperature
$temperature = $chip->read_temperature->get
Triggers a reading of the temperature sensor, returning a number in degrees C.
read_humidity
$humidity = $chip->read_humidity->get
Triggers a reading of the humidity sensor, returning a number in % RH.
