より湿度を検出することを特徴とする湿度検出器。In a humidity detector using a humidity sensor whose electrical resistance changes with changes in humidity, a metal conductor through which a current flows through the humidity sensor is connected between the first APD and the second LED, and the The first APD is connected to a first optical fiber carrying the output light from the first LED, and the first APD is connected to a first optical fiber carrying output light from the first LED.
The LED is connected to a second APD via a second optical fiber, and the first and second optical fibers constitute a transmission system of the humidity detector, thereby causing the first LED to emit light. A humidity detector, characterized in that humidity is detected by detecting the electrical output of the second APD.
