Re: SU-100 UV sensor

:) Sorry for 3 posts... I need options to remove or edit :)

ERROR: the value of my 0 is 0.0096 not 0.096...

Do you fix this on the next API ? Today I will send this to the correct place with this "HACK" ...

Re: SU-100 UV sensor

I can "hack" the code like this: float Apogee_SU100::read(void) { // object to manage ADC LTC ltc; //Enable SPI isolator for using the ADC digitalWrite(SPI_ISO_EN, HIGH); // ADC setup ltc.begin(); if (socket == XTR_SOCKET_B) { ltc.readADC(ADC_CH3); radiationVoltage = ltc.readADC(ADC_CH3); } if (sock...

Re: SU-100 UV sensor

In your code for Apogee_SP510 you have: ` ::read(void) if (socket == XTR_SOCKET_F) { ltc.readADC(ADC_CH2); radiationVoltage = ltc.readADC(ADC_CH2); } radiationVoltage-=0.046; <<<<<<<<<<<<<<<<<<<THIS HERE... If I do the same (subtract 0.046) for my sensor (SU-100) I have more "plausible" values... wh...

Re: SU-100 UV sensor

Hi,

https://i.ibb.co/rcdM78f/18h-apogee.png

During the night in Portugal yesterday.

The value is 0.0096 V... I have the same values in 2 diffrente sensors and P&S...

But I have a third old sensor that is correct.. (Agriculture_v20).

Re: SU-100 UV sensor

//Conversion from voltage into umol·m-2·s-1
radiation = radiationVoltage / 0.0002; << the value os result is V OR mV ? ?

SU-100 UV sensor

Hi,

My multiple sensors SU-100 return values allways > 49 umol/m^2/s-1 this is equal to 2 UV scale during the night... where is the error ?

Code: Select all

apogee.ON();
  apogee.read();
  radUV = apogee.radiation;
  apogee.OFF();

Kg/m^3 to Kg/g^3

HI,

For weather station example you have Kg/g^3 for "airDensity" instead of Kg/m^3... it's a bug correct ?
