Types

type SampleRate

type SampleRate struct {
	// contains filtered or unexported fields
}

type TMP006

type TMP006 struct {
	// Bus to communicate over.
	Bus embd.I2CBus
	// Addr of the sensor.

}

TMP006 represents a TMP006 thermopile sensor.

func New

func New(bus embd.I2CBus, addr byte) *TMP006

New creates a new TMP006 sensor.

func (*TMP006) Close

func (d *TMP006) Close() error

Close puts the device into low power mode.

func (*TMP006) ObjTemp

func (d *TMP006) ObjTemp() (float64, error)

ObjTemp returns the current obj temp reading.

func (*TMP006) ObjTemps

func (d *TMP006) ObjTemps() <-chan float64

ObjTemps returns a channel to fetch obj temps from.

func (*TMP006) Present

func (d *TMP006) Present() (bool, error)

Present checks if the device is present at the given address.

func (*TMP006) RawDieTemp

func (d *TMP006) RawDieTemp() (float64, error)

RawDieTemp returns the current raw die temp reading.

func (*TMP006) RawDieTemps

func (d *TMP006) RawDieTemps() <-chan float64

RawDieTemps returns a channel to get future raw die temps from.

func (*TMP006) Start

func (d *TMP006) Start() error

Start starts the data acquisition loop.
