Yesterday before sleep I replace LD271 IR LED and this morning oficially started data gathering.

On the pic you can see my morning glucosis test. Unfortunately the hour is wrong, need to fix it.

What I found strange is the variation of measurements in Green and Blue wavelengths. Have a look:

(Date Time R_max R_min G_max G_min B_max B_min Ir_max Ir_min)

2014/8/22 20:28:15 422 378 112 93 112 100 0 0

2014/8/22 20:38:57 402 362 93 77 93 83 1 0

2014/8/22 20:49:39 421 380 97 83 96 86 1 0

2014/8/22 21:0:13 436 393 106 90 105 95 1 0

2014/8/22 21:10:43 382 345 86 72 86 77 1 0

After replacement of LD271:

2014/8/23 0:39:55 55 49 1 0 1 0 25 22

2014/8/23 0:59:1 84 73 2 1 1 0 47 41

2014/8/23 9:7:35 97 87 3 1 2 1 53 47  

Small variation of Ir light was normal because LD271 was broken and needed replacement, but why suddenly we have very poor variation of Green and Blue? I'm pretty sure they work since they are visible on the device. Maybe it's not a defect?? Maybe we just found something that variates that much and can indicate something, for example very low body hydration?

I will examine this phenomena and I will keep you informed.
