A Design of High Smart Pressure Sensor Based on Microcontroller and BP Network


Article Preview

We introduce the high smart pressure sensor’s hardware-circuit design which based on Ultra-Low Power MSP430 MCU, analyze the BP network algorithm in temperature compensation to deal with the pressure sensor’s temperature drift, and collect pressure sensor’s temperature and pressure signals by MCU for offline training in BP network. The result shows that the MSP430 MCU can reduce system power and its rich exterior equipments can reduce the size of pressure sensor, the accuracy is improved by BP network algorithm, zero drift and time drift are best controlled.
