CPAP Flow Sensor

IDT and Renesas combine MCUs and flow sensors to create the ideal solution for CPAP and high-speed fluid flow control systems

Image of IDT/Renesas' CPAP Flow SensorRenesas' Synergy S7 series microcontrollers (MCUs) combined with IDT's FS2012 flow sensors control the speed of motors for enhanced flow accuracy. The CPAP flow sensor provides closed-loop feedback with an air flow sensor to determine motor failure and includes a built-in LCD controller for expanded system features. The combination is ideal for CPAP and high-speed fluid flow control systems. Power and timing devices are available to complete the solution.
