A sensing measurement scheme based on the optical fiber coupling optical driving converting probe is proposed. Using the optical feedback stabilized 5 mW LD as illuminant, the optical driving distance is 100 m. The power of designed low-consumption temperature-sensitive sensor probe is small to 2.2 mW. The design idea of this new sensor and the key technology of realizing optical driving are introduced in this paper. Experimental results show that the temperature sensor with high resolution can resist high-voltage and electromagnetic interference, and has high sensitivity and precision with 1000 Hz/°C.
