#102738 - That gives you a few options Responding to: ???'s previous message |
Depending on the range you have several options.
Use a voltage divider and a A/D converter. Use the "Resistor" to make a variable width pulse and measure it with the uP. Use the "Resistor" to make a variable frequency Ossilator and measure it with the uP. You need to figure out what your Range in Ohms is, and your range in what ever the sensors measures. Then once you know the bits you need and the accuracy you want you can pick a direction to go. |
