I saw that there has been a push to make a drug detector that can identify cannabis since it has been legalized. I was looking at mouser.com and found this ir sensor: https://www.mouser.com/ProductDetail/Pyreos/PY2435?qs=sGAEpiMZZMvkSJWT1okH7HZM1X5NjtfhYufzstUzGmFpPHtO%2FKJ1pA%3D%3D I also found these IR spectra
The ir sensor has filters for 8550nm(1169cm^-1), 8750nm(1143cm^-1), 9650nm (1036cm^-1), 12250nm (816cm^-1). Also your typical methane detector is at 3300nm(3000cm^-1) so alot of these line up with the absorbance peaks, do you think this will work as a detector? I have seen typically for organic compounds that have aromatic rings or pi bonds UV spectroscopy is typically used but i cant seem to find UV detectors online. Is there an easier way to do this? What is a good estimate of ppm that this ir detector could sense?
