What is an analog input?
An analog input converts a voltage level into a digital value that can be stored and processed in a computer. Why would you want to measure voltages? There are a multitude of sensors available which convert things like temperature, pressure, etc. into voltages.
Get temperature from a sensor using an analog input.
- Wire the output of the analog temperature sensor to a U3-HV as shown.
- Read the voltage on the computer to know the current temperature.
- This particular sensor outputs 0.01 volts per °F, so 0.76V corresponds with 76°F.
