Solar Radiation & UV Sensor whit CR3000


MiguelR Jul 7, 2010 06:15 PM

Hello,

Is the first time working with solar radiation sensors and radiation UV sensor, I'm doing the sensor readings as follows:

'Realizando Lecturas para el Sensor de Radiacion Solar CMP22
VoltDiff(RADTOT45_W,1,mV5000,6,True,0,_60Hz,1.0,0.0)
If RADTOT45_W <0 Then RADTOT45_W=0
RADTOT45_W = RADTOT45_W*1000/Sen_Rad
RADTOT45_MJ = RADTOT45_W * 0.00001

'Realizando lecturas para Sensor de Radiacion UV CUV 5
VoltDiff (RADUVHOR_W,1,mV5000,5,1,0,_60Hz,1.0,0.0)
If RADUVHOR_W < 0 Then RADUVHOR_W = 0
RADUVHOR_W = RADUVHOR_W*1000/Sen_UV

RADUVHOR_MJ = RADUVHOR_MJ * 0.00001

Sensor's that I'm using are for solar radiation CMP22 and
UV radiation CUV5 (Kipp & Zonen), the problem is that I show the same reading them, will have some examples to UV radiation sensors?

Thx

Why your use 5000 mv range, 20 mv is enough. You chose the worst soltuion. I think for CUV 5, please check your sensitivity. Most of UV will less than 70 W/m2. Select your best range then.

the cuv5 gives an output of 0-3000mV, the sensitivity is as follows:

'Sensibilidad en uVolts/Watt/m2 tal como lo muestra el sensor CMP22
Const Sen_Rad = 8.46
'Sensibilidad en uVolts/Watt/m2 tal como lo muestra el sensor CUV5
Const Sen_UV = 4.33
