Abstract:

Based on the DSP processor, an intelligent guide instrument was designed using ultrasonic sensor, temperature sensor and micro depth sensor, the guide instrument has functions of the location, water depth, temperature measurement and intelligent alarm, and has prompt functions of voice broadcast and night warning lights. The paper focuses on the application of micro water depth sensor in intelligent guide instrument. The experimental results show that the micro water depth sensor can effectively measure water depth in the road surface, and has high detection precision and security for the blind trip on rainy day.
