UPM module for the GUVA-S12D UV sensor

    // This was tested with the Grove UV Sensor module.
    // It has a sensing range from between 240-370nm.  It's strongest
    // response is around 320-360nm.

    // Instantiate a GUVAS12D on analog pin A0
    upm::GUVAS12D *volts = new upm::GUVAS12D(0);

    // The higher the voltage the more intense the UV radiation.

    while (shouldRun)
    {
        cout << "Volts: " << volts->volts()
             << ", Intensity: " << volts->intensity()
             << " mW/m^2"
             << endl;

        sleep(1);
    }

Member Function Documentation

float value	(	float	aref,
		unsigned int	samples
	)

Deprecated:

This method is being replaced by the volts() and illumination() methods.

Gets the average voltage value from the sensor

Parameters

aref	Reference voltage in use (usually 5.0 V or 3.3 V)
samples	Number of samples to average over (currently ignored)

Returns

Average voltage reading

float volts

(

)

Gets the voltage value from the sensor

Returns

Voltage reading

float intensity

(

)

Gets the computed illumination intensity from the sensor in mW/m^2.

Returns

Intensity over the sensitive wavelengths in mW/m^2

Here is the call graph for this function:

void setScale

(

float

scale

)

Set sensor scale. This scale is applied to the intensity value before the offset is applied. Default is 1.0.

Parameters

scale

Scale to apply.

Here is the call graph for this function:

void setOffset

(

float

offset

)

Set sensor offset. This offset is applied to the intensity value before scaling. Default is 0.0.

Parameters

offset

Offset to apply.
