OPTOELECTRONIC DEVICE FOR MEASURING THE HUMIDITY OF SILKWORTH COCOONS
Keywords:
silkworm cocoons, humidity, optoelectronics, LED, photodiode, device, emission spectra, measurement accuracy.Abstract
The goal of this work was to create an optoelectronic device for measuring the humidity of silkworm cocoons based on mid-IR LEDs. An optoelectronic device has been developed for measuring the humidity of silkworm cocoons based on mid-IR LEDs, allowing measurements in real mode with an accuracy of 1.5%. In the optoelectronic device for measuring the humidity of silkworm cocoons, LEDs with emission spectra of 2.2 μm are used as a reference channel, and LEDs with emission spectra of 1.94 μm are used as a measuring channel. A scheme is proposed that ensures the main condition of two-wave optoelectronic devices, the temporal and temperature stability of the LED parameters and the equality of their initial reference, measuring radiation fluxes, which determine the measurement accuracy.
