The example code is as follows:<\/p>\n\n\n\n<p>Then, complete the switch sensor logic. When the switch is pressed and not pressed, there are two states. The example code is as follows:<\/p>\n\n\n\n<p>Then, when the switch is turned on, programming is implemented to rotate the motor and switch the sensor. Every time the sensor is pressed, the motor rotates for 1 minute. The example code is as follows:<\/p>\n\n\n\n<p>Finally, complete the programming of the ventilator. The example code is as follows:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"865\" height=\"781\" src=\"https:\/\/code.xedulab.com\/wp-content\/uploads\/2025\/02\/image-52.png\" alt=\"\" class=\"wp-image-2996\" srcset=\"https:\/\/code.xedulab.com\/wp-content\/uploads\/2025\/02\/image-52.png 865w, https:\/\/code.xedulab.com\/wp-content\/uploads\/2025\/02\/image-52-300x271.png 300w, https:\/\/code.xedulab.com\/wp-content\/uploads\/2025\/02\/image-52-768x693.png 768w\" sizes=\"(max-width: 865px) 100vw, 865px\" \/><\/figure>\n\n\n\n<p>Optimization and improvement plan.<\/p>\n\n\n\n<p>Interesting thinking: Can the switch be kept normally open to achieve intelligent control based on environmental changes.<\/p>\n\n\n\n<p>3.<strong>Reflection and discussion: What are the influencing factors of school environmental monitoring?<\/strong><\/p>\n\n\n\n<p>Experimental results<\/p>\n\n\n\n<p>Data records: Table 1 and Table 2<\/p>\n\n\n\n<p>Experimental conclusion: occlusion, ambient temperature, soundproof environment, etc.<\/p>\n\n\n\n<p>5.Extension and Expansion<\/p>\n\n\n\n<p>Reflection and exploration:<\/p>\n\n\n\n<p>Question 1:<\/p>\n\n\n\n<p>Question 2:<\/p>\n<button class=\"simplefavorite-button has-count preset\" data-postid=\"558\" data-siteid=\"1\" data-groupid=\"1\" data-favoritecount=\"0\" style=\"box-shadow:none;-webkit-box-shadow:none;-moz-box-shadow:none;background-color:#ffffff;border-color:#ffffff;color:#686868;\"><i class=\"sf-icon-favorite\" style=\"color:#686868;\"><\/i>\u6536\u85cf<span class=\"simplefavorite-button-count\" style=\"\">0<\/span><\/button>","protected":false},"excerpt":{"rendered":"<p>\u6536\u85cf0 1.Teaching objectives (knowledge preparation) Get t&#8230;<\/p>\n","protected":false},"author":16,"featured_media":2998,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[86,81],"tags":[],"class_list":["post-558","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-environment","category-iot"],"_links":{"self":[{"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/posts\/558","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/users\/16"}],"replies":[{"embeddable":true,"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/comments?post=558"}],"version-history":[{"count":3,"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/posts\/558\/revisions"}],"predecessor-version":[{"id":3020,"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/posts\/558\/revisions\/3020"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/media\/2998"}],"wp:attachment":[{"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/media?parent=558"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/categories?post=558"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/code.xedulab.com\/index.php\/wp-json\/wp\/v2\/tags?post=558"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
