IOT - ib Tshaj Tawm Cov Ntaub Ntawv rau Thingspeak Siv ESP8266: 3 Cov Kauj Ruam

Tam sim no, IoT tab tom nthuav dav thiab ntau lub tshuab muaj cov ntaub ntawv rub tawm hla huab thiab txheeb xyuas cov ntaub ntawv. Cov ntsuas me me hloov kho cov ntaub ntawv ntawm huab thiab tus ua haujlwm ntawm lwm qhov kawg ua rau nws. Kuv yuav piav qhia ib qho piv txwv ntawm IoT.

Kuv tsab xov xwm no thiab kuv yuav qhia thiab qhia kom tshaj tawm cov ntaub ntawv rau Thingspeak siv ESP8266.

Kauj Ruam 1: Yuav Tsum Muaj Kev Koom Tes
