Whether it is a white-collar worker who pursues high quality life, or this generation of young mom and dad, is there any serious air pollution to affect yourself or your child's health? Does there have a good way to understand what they are currently in the environment, whether their family has an air quality problem? Thanks to the development of the Internet of Things, the smart home industry can say that it is thriving, there are some excellent environmental monitoring products. Today, today's love board will take you to understand and dismantle a simple and pure but unparalleled environmental monitoring equipment. .
Indoor and outdoor PM2.5 monitors C5
I saw this C5 naming, most people may not be in place, but in fact it has a high technical content. C5 is a PM2.5 environment monitoring device working through laser scattering principles. It is characterized by fast test speed, high accuracy, convenient operation.
C5 external packaging is simple, and important functions are also reflected on the box, simple.
In addition to the measurement of PM2.5, C5 also has time display (Internet automatic school), information sharing and other functions.
C5's R & D company is a sea-enhancement, which is a solution provider for providing Internet air detection and intelligent control.
Unpack
The interior of C5 is very simple, the fitting includes a C5 environment monitor host, a 5V / 1A adapter and a McIRousB line, a guarantee, and manual.
C5 design is relatively unique, triangular design, 60 ° inclined perspective, in line with the principle of ergonomics, placed on desktop and other places very stable.
The C5 base has more detailed information, such as the specific model, power supply, working principle, supported WiFi type, PM2.5 concentration representation.
Use
It is very convenient to use without downloading the app, just use the WeChat binding device to operate.
The networking configuration is very convenient, the whole process is less than 1 minute, the WeChat has some operations of the C5, such as on / off, timing, sharing and other functions, you can also see on / off, WiFi configuration, sharing, etc. in the C5 product. The capacitive touch button looks simple.
In addition to monitoring the PM2.5, C5 can also obtain the PM2.5 concentration of the local outdoor outdoor through the network. The specific test indicators are as follows:
Measuring range: 0 ~ 999 μg / cubic meter
Measurement accuracy: ± 15%
Response time: <5s dismantle="" from="" the="" actual="" test,="" the="" results="" of="" c5="" and="" millet="" air="" purifiers="" are="" basically="" consistent="" in="" the="" same="" position,="" and="" the="" response="" speed="" is="" really="" very="" fast,="" which="" is="" really="" good.="" but="" here="" will="" have="" questions,="" "how="" can="" i="" guarantee="" that="" c5="" achieves="" this="" accurate="" and="" rapid="" measurement="" result?"="" so="" next="" to="" a="" dismantling.="" at="" present,="" the="" structure="" of="" electronic="" devices="" is="" similar,="" as="" long="" as="" it="" is="" not="" those="" electronic="" products="" that="" claim="" waterproof,="" dismantling="" is="" still="" quite="" simple.="" remove="" the="" four="" fixed="" rubber="" pads="" at="" the="" bottom="" of="" the="" c5="" to="" see="" the="" screws,="" start="" from="" here.="" after="" the="" disconnection,="" see="" the="" layout="" of="" the="" c5="" is="" still="" a="" comparative="" empty,="" the="" functional="" module="" distribution="" is="" clear:="" the="" display="" portion,="" the="" wireless="" communication="" portion="" (wifi),="" the="" laser="" sensor="" portion="" (black="" part).="" first="" look="" at="" the="" screen,="" the="" core="" is="" the="" 16="" *="" 8="" led="" controller="" driver="" of="" holtek,="" the="" maximum="" display="" section="" is="" 16x8,="" with="" 133="" array="" scanning="" circuit,="" operating="" voltage="" 4.5v-5.5v,="" software="" configuration="" characteristics="" make="" it="" very="" suitable="" led="" applications,="" compatible="" with="" two-wire="" two-way="" i2c="" bus="" and="" most="" of="" the="" mcus,="" mainly="" used="" in="" industrial="" control="" indicators,="" digital="" clocks,="" thermometers,="" counters,="" led="" displays="" and="" other="" consumer="" electronics="" applications.="" next,="" the="" wireless="" communication="" heel="" sensor="" portion="" is="" then="" removed.="" relying="" on="" its="" own="" product="" failure="" and="" current="" chip="" integration,="" the="" separated="" wireless="" communication="" part="" looks="" quite="" simple,="" mainly="" qingke="" wifi="" module,="" a="" microsb="" power="" interface,="" a="" buzzer,="" two="" connected="" screens,="" the="" interface="" seat="" of="" the="" sensor="" portion.="" emw3165="" is="" a="" low-power="" embedded="" wifi="" module,="" which="" is="" integrated="" with="" a="" wireless="" rf="" chip="" and="" a="" model="" stm32f411ce,="" built-in="" "self-hosted"="" wifi="" network="" function="" library="" and="" application="" components.="" in="" addition,="" 2m="" bytes="" of="" film="" flash,="" 512k="" bytes="" of="" flash,="" 128k="" bytes="" of="" ram,="" and="" rich="" peripheral="" resources.="" there="" is="" no="" device="" on="" the="" back="" of="" the="" wireless="" communication="" board.="" the="" last="" part="" is="" a="" laser="" sensor="" module.="" is="" there="" a="" fan?="" isothermal="" use?="" not!="" from="" the="" working="" principle="" described="" by="" c5,="" it="" is="" to="" detect="" particles="" by="" laser="" scale,="" but="" if="" "sudden"="" is="" placed="" in="" a="" room,="" how="" to="" accurately="" measure="" pm2.5="" concentration="" in="" the="" air,="" obviously="" directly="" directly="" the="" circulation="" is="" not="" enough,="" especially="" in="" the="" sealed="" environment,="" then="" the="" effect="" of="" this="" small="" fan="" is="" obvious,="" used="" to="" speed="" up="" air="" flow,="" similar="" to="" active="" sampling="" air="" (inhalation).="" in="" addition,="" we="" can="" also="" see="" the="" words="" that="" engraved="" with="" heks,="" which="" is="" said="" to="" be="" the="" company's="" self-developed="" pm2.5="" high-precision="" laser="" sensor,="" which="" makes="" impurities="" without="" inclusion="" through="" laser="" scattering.="" wonderful="" is="" not="" as="" good="" as="" a="" dismantling,="" disassemble="" the="" module,="" except="" for="" this="" name="" magnetic="" suspension,="" there="" is="" another="" sensor="" board.="" although="" this="" part="" has="" a="" shield,="" it="" is="" still="" welded,="" but="" it="" is="" obvious="" that="" it="" is="" difficult="" to="" fall.="" remove="" the="" sound="" of="" the="" sensor="" board.="" thinking="" of="" the="" sensor="" board="" has="" a="" texas="" instrument's="" msp430g2433="" mixed="" signal="" microcontroller,="" further,="" there="" is="" a="" filter="" amplifying="" circuit="" in="" this="" micro-control="" front="" end.="" the="" other="" side="" of="" the="" board="" is="" a="" laser="" sensor="" device.="" then="" the="" hardware="" framework="" of="" the="" entire="" board="" is="" quite="" clear,="" the="" approximate="" working="" principle="" can="" refer="" to="" the="" following="" figure.="" be="" small="" knot="" c5="" not="" only="" accurately="" measures="" the="" indoor="" outdoor="" pm2.5="" concentration,="" but="" also="" an="" electronic="" clock="" of="" the="" internet="" automatic="" school,="" but="" also="" supports="" wechat="" one-click="" sharing="" test="" results.="" if="" there="" is="" conditional,="" it="" can="" be="" used="" in="" combination="" with="" the="" air="" purifier="" to="" achieve="" smart="" linkage.="" easily="" achieve="" the="" best="" intelligent="" interactive="" scene="" of="" smart="" homes;="" it="" is="" not="" difficult="" to="" find="" through="" dismantling,="" although="" it="" is="" just="" a="" pm2.5="" concentration="" detector,="" but="" the="" intrinsic="" but="" also="" the="" high-precision="" laser="" sensor,="" which="" is="" uniquely="" developed="" by="" heck,="" from="" hk.="" this="" is="" visible,="" any="" product,="" if="" there="" is="" competitive="" in="" the="" market,="" then="" the="" company's="" technical="" accumulation="" is="" also="" particularly="" important,="" otherwise="" it="" can="" only="" be="" a="" cost-effective="" assembly="" plant.="">
