Abstract: PURPOSE:To achieve a higher measuring accuracy, by connecting a light emitting element to an output terminal of an operational amplifier while an electric resistor is connected in series to the light emitting element to make up for temperature characteristic of the light emitting element. CONSTITUTION:In a sensor 1, a voltage is applied to an operational amplifier 100 from a storage battery B and the voltage being amplified is applied to a light emitting element 9 through output terminals (m) and (n) to emit light. Out of the light of the element 9, a part is directed to a light transmitting body 3, totally reflected on the internal side thereof and passes through the light transmitting body 3 to be incident into a light receiving element 14. Photoelectric characteristic of the elements 9 and 14 varies with changes in environmental temperature or the like in which the sensor 1 is arranged. The element 9 is incorporated into a temperature compensation circuit D and hence, photoelectric characteristic of the elements 9 and 14 changes with a rise in the ambient temperature. Thus, even under such a circumstance that an output of the sensor 1 is forced to lower, the voltage of the element 9 falls and a voltage drop generated in a resistor 101 by a current I flowing through the element 9 and an electric resistor 101 is controlled to increase the voltage and the current I rises to make up for photoelectric characteristic or the like of the elements 9 and 14.
