Which sensor category would monitor environmental conditions such as wind and precipitation, often via an integrated device?

• A. Weather station
• B. Flow
• C. Location
• D. Power

Answer: (A)

Monitoring environmental conditions like wind and precipitation is best addressed by a weather station. A weather station is built to measure climate parameters, often in an integrated device that combines sensors such as an anemometer for wind speed and direction, a rain gauge for precipitation, and typically temperature and humidity sensors as well. This centralized setup provides local weather data that irrigation designers use to estimate evapotranspiration and adjust scheduling accordingly. The other options don’t capture atmospheric measurements: a flow sensor tracks water movement, not weather; a location sensor indicates geographic position rather than environmental conditions; and a power sensor relates to energy, not atmospheric data.
