1.8;">为了解决非电子气象站没有联网功能，导致数据无法上云的问题，本项目设计了一款基于ESP12F和BME280模块的低功耗气象站，使用一节18650电池供电。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">其中，低功耗是本项目需解决的核心问题，只有将系统待机功耗以及整体功耗降低，才能让气象站长时间工作而无需充电。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">本项目可采集温度、湿度、气压数据，并通过MQTT上传至云端数据库，用户可从Grafana数据大屏查看气象信息。</p> <p class="paragraph text-align-type-left pap-line-1.3
