Saib Xyuas Tsev/Chav Ua Haujlwm Kub ntawm koj lub Desktop

Txhawm rau saib xyuas chav lossis chaw haujlwm lossis txhua qhov chaw uas peb tuaj yeem siv txoj haujlwm no thiab qhov ntawd tau qhia nrog ntau cov ntsiab lus zoo li duab, ntsuas kub lub sijhawm thiab ntau ntxiv.

Peb siv:

Ua ntej tshaj plaws, peb yuav tsum ua tus account ntawm IoT platform no, thiab tso tus lej no rau ntawm koj li Wemos DI thiab cuam tshuam koj lub LM35 sensor nrog Wemos D1 raws li qhia hauv daim duab thiab tom qab ntawd ua qee cov kauj ruam ntawm Iot platform raws li qhia hauv ppt.

Qhia PPT kom paub ntau ntxiv txog IoT platform.

Koj yuav tsum coj koj tus lej txoj haujlwm (nws yuav muab los ntawm yamIO. AI, raws li qhia hauv PPT) thiab xa mus rau microcontroller.

Kauj Ruam 1: Kauj Ruam Tus Txheej Txheem ntawm Txoj Haujlwm no

Kauj ruam 2: Code

Koj yuav tsum tso cov cai no rau hauv koj lub micro tswj. Ntawm no kuv tab tom siv wemos d1 thiab yuav tsum tau import yam koj yuav tsum tau hloov koj li wifi SSID thiab Password. (Ntawm no kuv yog SSID: DDIK Makadia thiab Password: kidd123456789)

Kauj Ruam 3: Daim duab

Daim duab
Daim duab

Koj yuav tsum txuas koj lub LM35 sensor raws li qhia hauv daim duab.

LM35 Sensor:

Kev Siv Hluav Taws Xob: 4-20V 3 tus pin: VCC, GND, SIGNAL SIGNAL tus lej hloov pauv qhov hluav taws xob raws li qhov ntsuas kub LM35 yog 3 tus lej ntsuas kub uas xav tau VCC thiab GND thiab rov qab ntxiv tus lej thib peb ntxiv rau peb tso tawm analog. Rau nws tus pin teeb tsa xa mus rau Circuit Diagram hauv qab no. Cov txiaj ntsig no tau muab rau ADCs tam sim no hauv AtMega 16 IC uas raws li tus lej xam qhov ntsuas kub hauv ° C hom. LM35 series yog qhov ntsuas sib xyaw ua ke-ntsuas kub ntsuas, nws qhov hluav taws xob tso tawm yog qhov sib npaug rau Celsius (Centigrade) kub. LM35 yog li muaj qhov zoo dua li ntsuas qhov ntsuas kub ntsuas hauv ° Kelvin.

Wemos D1:
