Lux Meter Module – Light Meter Schematic

  LUX Meter project has been design to measure the illumination.  Illumination is luminous flux falling on surface area of photo diode.  This illumination converted to corresponding voltage using Op-Amp circuit. Supply 9 VDC PP3 Battery @ 20 mA  Onboard Photo Diode  Onboard preset for calibration  Range selection via jumper 10mV/LUX, 1mV/LUX, 0.1mV/LUX  Interfacing is via berg connector  Power-On LED
