Thanks, you don't know how big relief this is for me. For a moment I thought the whole project was lost...
So if I switch the 2 lights lets say every quarter seconds, than I will get a wave signal at the output of the sensor.
Does that mean that in a simplified model, the wave's peak is at a...
with the second desing (2 different spectra UV leds) stability would not be a problem, as the leds light stay constant after reaching operating temperature. However with the low signal difference, I'll probably have to look into signal amplifyers and other circuitry to cancel electrical noise
Putting the light sources at the intake part would probably heat the measuring tube up, which would distort the measurement. I was expecting a reading anywhere between 10 and 50ppb, however I've just come across a HUGE miscalculation... The equation I used was the following...
Hi there,
I'm working on a project where I'm trying create a sensor to measure the relatively lower concentrations of O3 at ground level. The main idea is to use the unique spectral characteristics of O3, shine a UVC light (at 254nm, where the absorption cross section is the highest) through...
