The Temperature Sensor measures the temperature at the tip of its metal probe. You can measure the temperature in either degrees Celsius (°C) or degrees Fahrenheit (°F).

You can use the temperature sensor, for example, to measure the air temperature around your robot, or to track changes in water temperature.

Temperature Sensor Data

The Temperature Sensor can give the following data:

Data	Type	Range	Notes
Degrees Celsius	Numeric	-20 to 120	Temperature in degrees Celsius (°C)
Degrees Fahrenheit	Numeric	-4 to 248	Temperature in degrees Fahrenheit (°F)

Examples Using the Temperature Sensor

Some examples of how you can use the Temperature Sensor in your program are shown below.

Example 1: Beep when the Sensor Gets Warmer

This program has the robot make a beep sound once the temperature at the end of the probe rises by 5°F. The Program uses the Wait block in the Temperature Sensor – Change – Fahrenheit mode to wait for the temperature of the probe to increase by 5°F.

Tips and Tricks

Try warming the probe with your hands while running this program.

Example 2: Display “Hot” or “Cold” depending on the Temperature

This program changes the display to show “Hot” or “Cold” depending on whether the temperature is greater than 80°F. The program uses a Switch block in the Temperature Sensor – Compare – Fahrenheit mode to choose between two different Display blocks.

Tips and Tricks

While running this program, try moving the temperature sensor probe between glasses of hot and cold water.

Example 3: A Temperature Controlled Motor

This program varies the speed of a motor based on the temperature of the temperature sensor. It uses the Temperature Sensor block in Measure – Celsius mode to measure the temperature. The result is connected to the Power input of a Medium Motor block using a data wire.

Tips and Tricks

Try sampling the temperature of different objects while this program is running.

Temperature Sensor Blocks and Modes

The table below shows all of the programming blocks and modes that you can use with the Temperature Sensor.

Block	Mode	Use
Wait	Temperature Sensor - Compare	Wait for the temperature to reach a certain value.
Wait	Temperature Sensor - Change	Wait for the temperature to change by a certain amount.
Loop	Temperature Sensor	Repeat a sequence of blocks until the temperature reaches a certain value.
Switch	Temperature Sensor	Choose between two sequences of blocks based on the temperature.
Temperature Sensor	Measure	Measure the temperature, and get the result on a Numeric data wire.
Temperature Sensor	Compare	Compare the temperature to a threshold, and get the result on a Logic data wire.
