Types

type Device

type Device struct {
	Address uint8
	// contains filtered or unexported fields
}

Device represents a SHT4x sensor

func New

func New(bus drivers.I2C) Device

New creates a new SHT4x connection. The I2C bus must already be configured.

func (*Device) ReadTemperatureHumidity

func (d *Device) ReadTemperatureHumidity() (temperatureMilliCelsius int32, relativeHumidityMilliPercent int32, err error)

ReadTemperatureHumidity starts a measurement and then reads out the results. This function blocks while the measurement is in progress.

Temperature is returned in [degree Celsius], multiplied by 1000, and relative humidity in [percent relative humidity], multiplied by 1000.
