4Question

Which sensor would a weather robot use to measure humidity?

5Question

Why is a protective enclosure important for an outdoor weather robot?

6Question

A robot records a temperature of 18°C at 8:00 a.m. and 24°C at 2:00 p.m. What is the change in temperature?

7Question

A weather robot measures wind speed every 10 minutes. How many measurements will it take in 1 hour?

8Question

What is the difference between a sensor and an actuator in a weather robot?

9Question

11Question

A barometric pressure sensor shows a steady drop over several hours. What type of weather change might this suggest?

12Question

Why is data logging useful in a weather-monitoring robot?

13Question

A robot collects temperature data every 5 minutes for 2 hours. How many data points does it collect?

14Question

What is one advantage of using a robotic weather station instead of manual observations?

15Question

16Question

Why should a weather robot sample data at the same time intervals each day?

17Question

A soil-moisture sensor is added to a weather robot. Why might this be useful in agriculture?

18Question

If a robot is powered by a solar panel, why might cloudy weather affect its operation?

19Question

A weather robot must report wind direction. What kind of sensor system would it need, and why?

20Question

A robot records these temperatures: 14°C, 16°C, 18°C, 17°C, and 15°C. What is the average temperature?

21Question

Explain why a weather robot should be able to detect extreme conditions such as heavy rain or strong wind.

22Question

Design question: What three sensors would you include in a basic weather robot for a school rooftop station, and what would each measure?

23Question

A robot needs to send a warning when temperature is above 35°C and humidity is below 20%. Describe a simple decision rule using an if-then statement.

24Question

A weather robot loses power during a storm. What backup features or design choices could help prevent data loss? Name two.

25Question

Challenge: A town wants a robot weather station that can predict dangerous weather better than a basic station. Describe two improvements to the robot's design or data processing that would help, and explain why.

Answer Key

#	Answer
1	Weather is the short-term condition of the atmosphere at a specific place and time.
2	Examples include temperature, humidity, air pressure, wind speed, rainfall, and light level.
3	A temperature sensor or thermistor.
4	A humidity sensor.
5	It protects electronics from rain, wind, dust, and extreme temperatures.
6	6°C.
7	6 measurements.
8	A sensor collects data from the environment, while an actuator performs an action such as moving a cover or sounding an alert.
9	Calibration helps the sensors give accurate and reliable measurements.
10	It should activate protection, such as closing a cover, moving to shelter, or sending an alert.
11	It may suggest an approaching storm or unsettled weather.
12	It allows the robot to store measurements over time so trends and patterns can be analyzed.
13	24 data points.
14	It can collect data automatically and continuously without needing a person present.
15	8°C over 3 hours, so the average rate is about 2.67°C per hour.
16	Using consistent intervals makes the data easier to compare and analyze accurately.
17	It can help farmers monitor conditions related to watering, plant health, and weather effects on soil.
18	Cloudy weather can reduce sunlight, which may lower the amount of electrical power generated.
19	It would need a wind vane or directional wind sensor because it can detect the direction air is moving.
20	16°C.
21	It can protect itself, prevent damage, and provide alerts so people can respond safely.
22	Possible answer: temperature sensor for air temperature, humidity sensor for moisture in the air, and barometric pressure sensor for atmospheric pressure. Other valid sensor choices are acceptable if matched to the weather variable.
23	Example: If temperature is greater than 35°C and humidity is less than 20%, then send a heat warning.
24	Possible answers: battery backup, nonvolatile memory, automatic data syncing, or a safe shutdown system.
25	Possible answers: add more sensors such as wind speed and pressure for broader data, use trend analysis or threshold alerts to detect patterns, or send data to a cloud system for comparison over time. These improvements help the station identify storm conditions earlier and make better warnings.
