الهواء تم تطويره بواسطة <a href='http://inovafitness.com/en/a/chanpinzhongxin/95.html'>Nova Fitness</a>، وهي شركة فرعية من جامعة جينان (شاندونغ).</p> <p>نظرًا لحجمه، فمن المحتمل أن يكون واحدًا من أفضل أجهزة الاستشعار من حيث الدقة: بينما تميل أجهزة الاستشعار الأخرى إلى التركيز على تقليص حجم المستشعر، اختار SDS 011 مقايضة الحجم مما يسمح له باستخدام مروحة أكبر. وكلما كانت المروحة أكبر، كانت الجودة أفضل.</p> </section><h2><p>تحديد</p></h2><section> Spec sheet: <a href='/air/view/sensor/spec/SDS011-spec-v1.3'>SDS011-datasheet-v1.3</a> <br> <br> <p>هذه هي مواصفات SDS011. لا ينبغي للمرء أن يعتبر كل هذه القيم أمرا مفروغا منه لأنه غالبا ما يكون هناك فرق كبير بين ما يقال أنه ممكن وما هو ممكن في الواقع (وهذا هو السبب وراء قيامنا بإعداد جميع تجاربنا).</p> <ul><li> الإخراج: PM2.5، PM10 <li> نطاق القياس: 0.0-999.9 ميكروجرام/م 3 <li> جهد الإدخال: 5 فولت <li> الحد الأقصى للتيار: 100 مللي أمبير <li> تيار النوم: 2 مللي أمبير <li> وقت الاستجابة 1 ثانية <li> تردد إخراج البيانات التسلسلية: مرة واحدة/ثانية <li> دقة قطر الجسيمات: ≥0.3μm <li> الخطأ النسبي: 10% <li> نطاق درجة الحرارة: -20~50 درجة مئوية <li> الحجم المادي: 71 مم* 70 ملم * 23 ملم</ul> <p>لاحظ أن نطاق عمل الرطوبة SDS011 هو 0-70%. وهذا جيد جدًا، نظرًا لأن الرطوبة أعلى من 70%، تصبح القراءات غير قابلة للتحقق.</p> </section><h2><p>انظر من الداخل إلى المستشعر</p></h2><section> <p>تتمثل الهندسة الذكية في SD011 في استخدام PCB كجانب واحد من الغلاف (مما يسمح بتقليل تكلفة قائمة مكونات الصنف). يتم تركيب الصمام الثنائي على جانب ثنائي الفينيل متعدد الكلور (وهذا أمر إلزامي حيث ينبغي تجنب أي ضجيج بين الدايود وLNA). يتم تثبيت الليزر على الصندوق البلاستيكي ومتصل بثنائي الفينيل متعدد الكلور عبر سلك طائر.</p> <center> <img src='/air/images/sensors/sds011-inside.jpg' style='width:800px;max-width:100%;'> </center> <p>أكبر مشكلة في هذا التصميم هي أن المستشعر بالكامل بالداخل أصبح غبارًا جدًا، كما هو موضح في الصورة أدناه بعد تشغيله على مدار الساعة طوال أيام الأسبوع لأكثر من 6 أشهر. هذا في الواقع ليس سيئًا للغاية نظرًا لأن الغبار لم يتراكم على الصمام الثنائي ولا على الواجهة الأمامية لليزر. فيما يتعلق بالمروحة، يعد تراكم الغبار "سلوكًا طبيعيًا" يُرى أيضًا على الديلوس.</p> <center> <img src='/air/images/sensors/sds011-dust.jpg' style='width:500px;max-width:100%;'> </center> <p>أخيرًا، فيما يتعلق بثنائي الفينيل متعدد الكلور، هل الأمر بسيط جدًا. وحدة المعالجة المركزية الرئيسية عبارة عن معالج 8 بت (مخدوش لمنع إجراء هندسة عكسية!). تحت التدريع يمكن العثور على مكبر للصوت منخفض الضوضاء (مثبت مباشرة على الجانب الآخر من الصمام الثنائي).</p> <center> <img src='/air/images/sensors/sds011-pcb.jpg' style='width:420px;max-width:100%;'> </center> </section><h2><p>إعداد التجربة</p></h2><section> <p>هناك نوعان من SDS011 في مكان واحد. SDS011i #1 هو جهاز استشعار تم استخدامه في الهواء الطلق لعدة أشهر. يعد SDS011 #2 مستشعرًا جديدًا تمامًا (منذ سبتمبر 2016).</p> </section><h2><p>معلومات الوقت الحقيقي</p></h2><section> Current
