Thermometer sensors are used to measure temperature in various environments. In robotics, these sensors can help robots detect and react to their surroundings, such as avoiding areas with high temperatures or maintaining a specific temperature range.

Thermometer sensors have numerous applications in robotics, including:

• Monitoring the temperature of a robot's components to prevent overheating
• Controlling the temperature in a greenhouse by adjusting ventilation and heating systems
• Enabling a robot to navigate through areas with varying temperatures, such as a rescue robot searching for survivors in a fire

The microbit has a built-in temperature sensor that can be used to read the current temperature. To read the temperature, you can use the following code:

basic.showNumber(input.temperature())

This code will display the current temperature in Celsius on the microbit's LED matrix.

While thermometer sensors are useful in many applications, they have some limitations:

• They may not provide accurate readings in extreme temperature ranges
• They can be affected by other heat sources, such as motors or electronic components
• They may require calibration to ensure accurate readings

Despite these limitations, thermometer sensors remain an essential tool in many robotics projects.
