摘要
以Arduino UNO R3为核心,采用SDP810数字式差压传感器和8通道I2C开关,设计了一种多路差压计,给出了软硬件设计方案。测试结果表明,该差压计成本低,在低压和低流量下具有高灵敏度,为气体差压监控提供了一种解决方案。
Based on Arduino UNO R3,using digital differential pressure sensor SDP810 and 8-Channel I2C switch,this paper designs a multi-channel differential pressure flowmeter to measure gas different pressure, and software and hardware are presented.The test results show that differential pressure flowmeter achieve the highest sensitivities at low pressures and flow,and also has low cost,which provides a solution for the differential pressure monitoring of the gas.
