Ntawm no koj tuaj yeem pom ib qho rov ua dua ntawm kev siv OneWire nrog ob peb tus pin ntawm ESP-01. Cov cuab yeej tsim hauv cov lus qhia no txuas rau Wifi network ntawm koj xaiv (koj yuav tsum muaj daim ntawv pov thawj …) Sau cov ntaub ntawv nkag siab los ntawm BMP280 thiab DHT11, thiab xa cov ntaub ntawv khaws tseg mus rau ThingSpeak channel tau muab rau kuv. Kuv xav tias koj paub yuav ua li cas rub cov duab kos rau koj ESP-01, yog li kuv yuav tsis mus rau hauv cov ntsiab lus ntawd. nrog max 3.3V DC. Not ntau cov ntawv ntxiv, nyeem yuav tsum ncaj qha los ntawm qhov no.

Kauj Ruam 1: Kauj Ruam 1: BOM

Kho vajtse:

1 x Wifi module: ESP-01 (kuv siv 1024 KB version)

1 x Siab thiab Kub sensor: BMP280

1 x Vaum thiab Kub sensor: DHT11

1 x Tus Tswj Hluav Taws Xob AMS1117 (xaiv tau rau lub zog ncaj qha, lossis koj tuaj yeem siv lwm yam muaj peev xwm tswj hwm koj qhov hluav taws xob nkag mus rau qhov ruaj khov 3.3V)
