ASSIMILATE SENSORS yog ib puag ncig cov cuab yeej uas tau ntxiv cov txheej txheem kho vajtse thiab software tsis ua haujlwm, ua rau nws muaj peev xwm ua kom tau cov hom tshiab kom ntxiv rau ASSIMILATE SENSOR HUB thiab nyeem tau tso rau hauv MQTT server yam tsis ntxiv kev sau npe.
Qhov ASSIMILATE SENSOR dumps 3 yam:
LPG (Tshooj Ib lab), CO (PPM), SMOKE (PPM)
Kauj Ruam 1: Cov Ntaub Ntawv thiab Cov Cuab Yeej
Nov yog I2C MQ2 BRICKBill Cov Khoom Siv thiab Sau Npe.

Kauj ruam 2: Sib dhos
Ua raws cov lus qhia tsim ntawm IOT123 - I2C MQ2 BRICK. Cia lub MQ2 sensor cais tawm ntawm lub Circuit Court.
- Tshem tawm 3P txiv neej lub taub hau los ntawm MQ2.
- Nyob tom qab ntawm MQ2, ntxig ib lub xaim daj rau hauv "A0" thiab cov laug.
- Nyob tom qab ntawm MQ2, ntxig xaim dub rau hauv "GND" thiab cov laug.
- Nyob tom qab ntawm MQ2, ntxig ib txoj hlua liab rau hauv "VCC" thiab cov laug.
- Ceev cov ntawv luam tawm 3D mus rau MQ2 pawg thawj coj nrog 4G x 10mm ntsia hlau.
- Ntxiv ib txheej nyias nyias (~ 0.6mm) ntawm cov kua nplaum kub mus rau qhov kawg ntawm tus tuav. Cia nws txias. Trim cov kua nplaum nrog riam riam kom txog thaum zoo haum hauv 3D luam tawm hau.
- Ntxig MQ2 thiab kos rau hauv 3D luam tawm lub hau, khoov me ntsis kom nws ntog hauv qab BRICK hauv lub hauv paus thaum sib sau ua ke.
- Nyob tom qab ntawm BRICK, ntxig cov xaim daj rau hauv YELLOW1 thiab cov laug.
- Nyob tom qab ntawm BRICK, ntxig cov xaim dub rau hauv BLACK1 thiab cov laug.
- Nyob tom qab ntawm BRICK, ntxig cov xaim liab rau hauv RED1 thiab cov laug.
- Ntxig lub BRICK rau hauv 3D Luam cov hauv paus grooves, nrog 90 tus pin txuas nrog cov voids.
- Tig thiab nias saum toj ntawm cib mus rau qhov nyuaj. Yog tias sab saum toj ntawm BRICK thiab lub hauv paus tsis sib haum, tshem tawm BRICK thiab ntxuav ib qho kab xev uas yuav tsum tso tseg txoj kev sib dhos thiab rov ua dua.
- Thaum qib, ntswj ntsia hlau rau hauv lub qhov qis txuas nrog BRICK rau lub hauv paus.
- Muab cov xov hlau tso rau hauv lub hauv paus ntawm ib sab ntawm tus laug laug mus rau BRICK.
-
Ceev lub hau rau hauv paus nrog 4G x 6mm ntsia hlau.
Kauj Ruam 3: Xeem
Kev sim (ntawm theem no) tuaj yeem zoo ib yam nrog BRICK hauv qab.
Tsuas yog txuas cov xov hluav taws xob txuas rau tib tus pin ntawm sab hauv qab ntawm ASSIMILATE SENSOR.
Kauj Ruam 4: Cov Kauj Ruam Tom ntej
Muaj cov lej txaus thiab cov lus piav qhia rau koj kom pib koj tus kheej ASSIMILATE SENSOR NETWORK.
Lossis koj tuaj yeem tshawb xyuas rov qab ntawm no kom paub ntau ntxiv thiab MQTT Hub hauv ob peb lub asthiv tom ntej.
