STM32F103VET6 microcontroller as the control core of the system, based on the precise control of il_lumination time, delay time, and pulse acquisition time, cooperating with single photon counter and selecting filters with high transmittance, deep cutoff degree and precise wavelength control, design a bio-delayed spectra detection system. Taking the wheat as the test object, the result shows that:the delayed luminescence intensity of the wheats fo_cus mainly at a wavelength of 525 nm, and there is an obvious peak around 640 nm.
