Abstract

PURPOSE: To make it possible to detect a temperature and light at the same time by forming two couples of electrodes on a thermosensitive plate substrate and by using one couple for a thermal sensor and the other couple for a photo sensor with a photosensitive resistor formed between the both.
CONSTITUTION: Two couples of electrodes 2 and 3 are formed on the surface of thermosensitive plate substrate 1. Between electrodes 3, photosensitive resistor 4 such as Se CdS is formed overlapping with electrodes 3. As a result, a single sensor can detect a temperature and light both at the same time; the temperature is detected by measuring the resistance between electrodes 2, and the light is by measuring the resistance between electrodes 3. In another way, substrate 1 is electrically insulated from electrode 3 by glass, SiO2 or the like to remove the influence of a temperature higher than the measurement value of electrodes 3. In addition, the sensor is protected from an external atmosphere by being covered with an insulating and transparent layer. The sensor like this can be miniaturized as compared with two sensors used and suits to a miniature apparatus such as a camera, so that low cost and improved reliability can be realized.
