NAME
Device::Chip::HTU21D - chip driver for HTU21D
SYNOPSIS
use Device::Chip::HTU21D;
use Future::AsyncAwait;
my $chip = Device::Chip::HTU21D->new;
await $chip->mount( Device::Chip::Adapter::...->new );
printf "Current temperature is is %.2f C\n",
await $chip->read_temperature;
DESCRIPTION
This Device::Chip subclass provides specific communication to a TE
Connectivity HTU21D attached to a computer via an I�C 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 in an await expression return Future
instances.
read_config
$config = await $chip->read_config;
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
await $chip->change_config( %changes );
Writes updates to the user register.
METHODS
read_temperature
$temperature = await $chip->read_temperature;
Triggers a reading of the temperature sensor, returning a number in
degrees C.
read_humidity
$humidity = await $chip->read_humidity;
Triggers a reading of the humidity sensor, returning a number in % RH.
