Above Threshold Warning of Temperature Data
Recommended for grades 9–14.
Introduction
In the following exercise, you will create a program using SensorDAQ’s Analog Express VI that records temperature data. The code will allow the user to display the data in Celsius or Fahrenheit units. In addition, a threshold value is compared to the temperature measurement and a message is displayed to alert the user when the temperature is above the threshold.
Objectives
In this exercise, you will
- Create a LabVIEW VI to collect temperature data.
- Become familiar with an Enumerated control.
- Warn the user when the temperature is above a threshold value.
- Incorporate code that makes decisions based on user input and numeric comparison.
Sensors and Equipment
This activity requires each of the following Vernier sensors and equipment (unless otherwise noted):
Additional Requirements
You will also need a SensorDAQ interface and LabVIEW software for data acquisition.
