Abstract

PURPOSE:To generate a sunburn alarm when the integrated amount of irradiation of ultraviolet rays reaches a prescribed limit by detecting the strength of the ultraviolet energy as the change of resistance value of a photoconductive substance and thereby changing the frequency of oscillation. CONSTITUTION:The intensity of the ultraviolet radiation is detected as the change of resistance value of the photoconductive element 1, and with the frequency decided by this resistance value and the capacity of a capacitor 11 an oscillator 2 performs an oscillation action, while performing the frequency division by the end of a required time interval. On the occasion, when the ultraviolet radiation is intensive, the resistance value becomes small, while the frequency of oscillation becomes high. And the pulse of the output voltage thus obtained is impressed on an SCD indication element 7. Furthermore, a buzzer 6 is made to actuate during the time set by the capacitor 51 and the resistance 52 of a buzzer circuit 5. After completion of a test for one cylce, by the operation of a switch 3, a erasing circuit is made to actuate to erase the SCD indication element 7. At this time, the oscillating circuit 2 is reset.
