Design of a Novel Mine-used Intelligent Water-pressure Sensor

The paper introduced design schemes of whole structure, main hardware circuits and software of a novel mine-used intelligent water-pressure sensor based on STM32F103RBT6. The sensor adopts design way of low power consumption circuit and time-sharing power supply way to make power consumption be 0.006 mA under idle condition and 0.5 mA under collection and sending condition.
