The multifunctional device is designed to measure wind velocity and temperature while providing unit conversion capabilities. It offers the ability to measure maximum, minimum, and average wind velocities. The device also features data holding, storing, and deleting functions for convenient data management. Additionally, it includes a low battery indicator and an audio alert when buttons are pressed. To conserve power, the device has an auto power off function that activates after 5 minutes of inactivity or when the fan becomes static. With a memory capacity of 100 records, users can easily review previous measurements. The large LCD display includes a backlight function for improved visibility in various lighting conditions. The wind handle can be elongated for flexible usage. The wind velocity range is from 0.3 to 30 m/s, while the air temperature range spans from -10 to 45 degrees Celsius (14 to 113 degrees Fahrenheit).
