A place without extreme light reflections.
The environment contains an ordinary, white fluorescent lamp without high frequency modulation. The
color temperature is 2856K and the illumination at the IR receiver is less than 10 Lux (Ev 10Lux)
The test transmitter is calibrated by using the circuit shown in figure 2. The radiation intensity of the
transmitter is adjusted until Vo=400mVp-p. Both, the test transmitter and the photo diode, have a peak
wavelength of 940nm. The photo diode for calibration is PD438B (λp=940nm, Vr=5V).
