    Conversion of Voltage to LUX

    Hello. I need some guidance again =)
    Its regarding the conversion of voltage level to equivalent LUX.

    As mentioned in prev. few threads, if you have seen it,
    basically, my circuit board is connected to a solar panel and is connected to a power supply (those laboratory DC power supply used in schools).
    The whole thing is connected to the computer via a RS232 Serial cable port.

    Thru the serial cable port, a voltage level is sensed from the Solar Panel and is displayed on the "Voltage Level in Volts(V)" -- See attach image

    >> Currently, i need guidance on how to convert the Voltage Level into equivalent LUX.



    I googled and found from this website >> http://www.emant.com/324003.page and it states that Lux = 1333 * Vo , so does it mean that i just type:

    Code:
    TextBoxLux.text = TextBoxVoltage.Text * 1333
    I'm not sure if this is the correct method to convert voltage level from the solar panel into equivalent LUX. If this method is wrong, please correct me. Thanks in advance !




    [Defination of LUX: The lux (symbol: lx) is the SI unit of illuminance and luminous emittance. It is used in photometry as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface]
