Adafruit_HTU21DF::Adafruit_HTU21DF

(

)

Constructor for the HTU21DF driver.

Member Function Documentation

begin()

bool Adafruit_HTU21DF::begin

(

TwoWire *

theWire = &Wire

)

Initialises the I2C transport, and configures the IC for normal operation.

Parameters

theWire

Pointer to TwoWire I2C object, uses &Wire by default

Returns

true (1) if the device was successfully initialised, otherwise false (0).

readTemperature()

float Adafruit_HTU21DF::readTemperature

(

void

)

Performs a single temperature conversion in degrees Celsius.

Returns

a single-precision (32-bit) float value indicating the measured temperature in degrees Celsius or NAN on failure.

readHumidity()

float Adafruit_HTU21DF::readHumidity

(

void

)

Performs a single relative humidity conversion.

Returns

A single-precision (32-bit) float value indicating the relative humidity in percent (0..100.0%).

reset()

void Adafruit_HTU21DF::reset

(

void

)

Sends a 'reset' request to the HTU21DF, followed by a 15ms delay.
