Member Function Documentation

begin()

bool Adafruit_MLX90614::begin	(	uint8_t	addr = MLX90614_I2CADDR,
		TwoWire *	wire = &Wire
	)

Begin the I2C connection.

Parameters

addr	I2C address for the device.
wire	Pointer to Wire instance

Returns

True if the device was successfully initialized, otherwise false.

readObjectTempC()

double Adafruit_MLX90614::readObjectTempC

(

void

)

Get the current temperature of an object in degrees Celcius.

Returns

double The temperature in degrees Celcius or NAN if reading failed

readAmbientTempC()

double Adafruit_MLX90614::readAmbientTempC

(

void

)

Get the current ambient temperature in degrees Celcius.

Returns

double The temperature in degrees Celcius or NAN if reading failed

readObjectTempF()

double Adafruit_MLX90614::readObjectTempF

(

void

)

Get the current temperature of an object in degrees Farenheit.

Returns

double The temperature in degrees Farenheit or NAN if reading failed

readAmbientTempF()

double Adafruit_MLX90614::readAmbientTempF

(

void

)

Get the current ambient temperature in degrees Farenheit.

Returns

double The temperature in degrees Farenheit or NAN if reading failed

readEmissivityReg()

uint16_t Adafruit_MLX90614::readEmissivityReg

(

void

)

Read the raw value from the emissivity register.

Returns

uint16_t The unscaled emissivity value or '0' if reading failed

writeEmissivityReg()

void Adafruit_MLX90614::writeEmissivityReg

(

uint16_t

ereg

)

Write the raw unscaled emissivity value to the emissivity register.

Parameters

ereg	The unscaled emissivity value

readEmissivity()

double Adafruit_MLX90614::readEmissivity

(

void

)

Read the emissivity value from the sensor's register and scale.

Returns

double The emissivity value, ranging from 0.1 - 1.0 or NAN if reading failed

writeEmissivity()

void Adafruit_MLX90614::writeEmissivity

(

double

emissivity

)

Set the emissivity value.

Parameters

emissivity

The emissivity value to use, between 0.1 and 1.0
