The water logging sensor based on the principle of infrared photoelectric detection has high sensitivity and fast response time,but the environmental natural light,water mist and other interference test accuracy.In this paper,through the optimization design of the material and structure of the optical probe,the accuracy of the sensor test is improved.Through the design of double-layer protective structure and the design of heating constant temperature,the interference of natural light,condensation and other environmental factors on the photoelectric test is avoided.A highly reliable infrared photoelectric water logging sensor is designed.
