Which sensor measures wind speed to shut off irrigation?

• A. Wind Sensor
• B. Flow Sensor
• C. Temperature Sensor
• D. Humidity Sensor

Answer: (A)

Wind conditions directly affect how water is distributed from sprinklers. A wind sensor provides real-time wind speed data to the irrigation controller, so the system can pause or shut off sprinklers when gusts reach a set threshold. This helps prevent water from drifting onto undesired areas and reduces evaporation losses, making the application more efficient and safe. The other sensors serve different purposes: a flow sensor measures how much water is moving through the system, not the air movement; a temperature sensor gauges air temperature, which influences scheduling but not automatic shutdown due to wind; a humidity sensor measures moisture in the air, which also doesn’t trigger wind-based shutoff.
