摘要

了解天气状况非常重要,因为它们会对农业、基础设施、水文等各种人类活动产生影响。影响天气的因素包括风速、温度和空气湿度。不过,在这项研究中,设计了一个微型气象站,不仅提供风速、温度和湿度信息,还提供太阳辐射信息。研究采用了多个传感器,包括 DHT11、风速计和高温计。研究结果表明,DHT11 在室内的误差为 1.4%,但在室外则增加到 9%。高温计的太阳直接辐射测量误差为 3.62%。然而,风速传感器仍然不稳定,这表明需要在未来的研究中加以改进。

ENVIRONMENTAL CONDITION MEASUREMENT SYSTEM WITH A MINI WEATHER STATION USING ESP32
Weather conditions are important to know because they have an impact on various human activities, such as agriculture, infrastructure, hydrology, and more. Several factors affect the weather, including wind speed, temperature, and air humidity. However, in this study, a mini weather station was designed to provide information not only on wind speed, temperature, and humidity but also on solar radiation. The research employed several sensors, including the DHT11, anemometer, and pyranometer. The research results indicate that the DHT11 error indoors is 1.4%, but it increases to 9% outdoors. The pyranometer shows a 3.62% error from direct solar radiation measurements. However, the wind speed sensor is still unstable, suggesting the need for improvement in future research.
