hey guys,
i'm working on a senior design project and i'm kind of stumped on this part of it. we have to design a ventilator for use in the developing world; part of our design is that when the pressure coming out of the device is too high, an led will light up - eg if the pressure is above 7cmH2O, a light will go off. I think we're going to have to start by buying a pressure sensor that converts pressure into voltage, but i have no idea what this circuit would look like. would appreciate any help!!!
thanks!
