UV sterilization automatic monitoring instrument

The utility model discloses an ultraviolet sterilization automatic monitoring instrument which is used for the ultraviolet sterilization of air in medical sterile environments and is composed of a probe, an A/D converter, a single-chip computer, and a controlled silicon control circuit. The probe converts the irradiation degree of ultraviolet rays transmit emitted by an ultraviolet lamp tube into electric signals and is connected with the single-chip computer through the A/D converter, and a relationship curve of the irradiation degree and the quantity of sterilizing agents is stored in the single-chip computer. When the quantity of ultraviolet rays emitted by the ultraviolet lamp tube reaches the quantity of sterilizing agents, the single-chip computer turns off the ultraviolet lamp through the controlled silicon control circuit. The utility model realizes the automatic monitoring in the process of ultraviolet sterilization, and the effect is ideal.
