destul de recent dezvoltat de <a href='http://inovafitness.com/en/a/chanpinzhongxin/95.html'>Nova Fitness</a> , un spin-off al universității din Jinan (din Shandong).</p> <p>Cu dimensiunea sa, este probabil unul dintre cei mai buni senzori în ceea ce privește precizia: în timp ce alți senzori tind să se concentreze pe micșorarea dimensiunii senzorului, SDS 011 a optat pentru un compromis de dimensiune care îi permite să folosească un ventilator mai mare. Și cu cât ventilatorul este mai mare, cu atât calitatea este mai bună.</p> </section><h2><p>Specificații</p></h2><section> Spec sheet: <a href='/air/view/sensor/spec/SDS011-spec-v1.3'>SDS011-datasheet-v1.3</a> <br> <br> <p>Aceasta este specificația pentru SDS011. Nu ar trebui să considerăm toate acele valori ca fiind de la sine înțeles, deoarece există destul de des o mare diferență între ceea ce se spune că este posibil și ceea ce este de fapt posibil (și de aceea ne înființăm toate experimentele).</p> <ul><li>Ieșire: PM2.5, PM10<li> Domeniu de măsurare: 0,0-999,9μg/m3<li> Tensiune de intrare: 5V<li> Curent maxim: 100mA<li> Curent de somn: 2mA<li> Timp de răspuns 1 secundă<li> Frecvența de ieșire a datelor seriale: 1 dată/secundă<li> Rezoluția diametrului particulelor: ≤0,3μm<li> Eroare relativă: 10%<li> Interval de temperatură: -20~50°C<li> Dimensiune fizică: 71mm*70mm*23mm</ul> <p>Rețineți că intervalul de lucru al umidității SDS011 este de 0-70%. Acest lucru este atât de bun, deoarece peste 70% umiditate, citirile devin nereale.</p> </section><h2><p>Priviți în interior la senzor</p></h2><section> <p>Ingineria inteligentă a SD011 este de a folosi PCB-ul ca o parte a carcasei (permițând reducerea costului BOM). Dioda este montată pe partea PCB (acest lucru este obligatoriu deoarece orice zgomot între doid și LNA ar trebui evitat). Laserul montat pe cutia de plastic și conectat la PCB printr-un fir zburător.</p> <center> <img src='/air/images/sensors/sds011-inside.jpg' style='width:800px;max-width:100%;'> </center> <p>Cea mai mare problemă a acestui design este că întregul senzor din interior devine foarte praf, așa cum se arată în imaginea de mai jos, după ce a funcționat 24/7 timp de mai mult de 6 luni. Acest lucru nu este chiar atât de rău, deoarece praful nu s-a acumulat pe diodă și nici pe front-end-ul laserului. În ceea ce privește ventilatorul, acumularea de praf este un „comportament normal” observat și pe dylos.</p> <center> <img src='/air/images/sensors/sds011-dust.jpg' style='width:500px;max-width:100%;'> </center> <p>În sfârșit, în ceea ce privește PCB-ul, este destul de simplu. CPU principal este un procesor de 8 biți (zgâriat pentru a preveni inginerie inversă!). Sub ecran se găsește amplificatorul de zgomot redus (montat direct pe partea opusă a diodei).</p> <center> <img src='/air/images/sensors/sds011-pcb.jpg' style='width:420px;max-width:100%;'> </center> </section><h2><p>Configurarea experimentului</p></h2><section> <p>Există două SDS011 colocate. SDS011i #1 este un senzor care a fost folosit în exterior de câteva luni. SDS011 #2 este un senzor nou-nouț (din septembrie 2016).</p> </section><h2><p>Date în timp real</p></h2><section> Current <b>BAM</b> readings are: <ul id='bam25Info'> <li>PM<sub>2.5</sub> mass in
