Today, we measured the response of the photo sensor.

• Because LED blight weakly, we introduced the power supply and load on LED with 0.08 A and 1.62V (=113mW < 120mW).
• Because of much noise on signal, we filtered original signal (K1:AOS-IYC_WAB_PS_INF_S1_INMON) using first 1Hz lowpass filter. Then we used OUTMON signal to measure the photo sensor response.
• We comapred reflector surface is covered by alminum and surface is not covered. Attached image shows the setup with alminum cover.
• Response is shown in second attached file. we think that at the around 6mm response of the photo sensor somhow is changing because of background room light or multple reflection.

Tomorrow, we are going to turn off the room right to measure on the state of a dark.
