So I have a design project for one of my classes that is requiring me to find a sensor or transducer that can send data via PWM and integrate it into the microcontroller development boards we designed and built. I'm being indecisive on what part I want to actually use and I am also new to sensors that use PWM (I'm used to analog sensors) so I figured I's ask GATR. I'm looking for, for example, accelerometers, inclinometers, temp, ect and an idea on an interesting way to use it. It is major bonus if it accepts 5V Vdd. I'm looking for links to companies that offer small quantity samples. If the part is ridiculously awesome but they don't have samples post it anyways, I have a stipend up to $60...
