PInt@t10n: Smart Plant Monitoring System: 9 trin

Dette projekt blev oprettet som en test for ibm iot cloud. Vi bruger en esp-8266 til at sende og modtage data til og fra ibm-skyen. Kommunikationen mellem esp og ibm -skyen sker gennem MQTT.

For at håndtere alle data og for at præsentere brugeren for en brugergrænseflade bruger vi node-rød. Det er meget begyndervenligt.

For at komme i gang har du brug for:

• Esp-8266
• dht 11/22 temp/fugtføler
• lysfølsom diode (lysmåling)
• summer
• jordfugtighedsføler
• ibm cloud -konto

Trin 1: Tilslut dine sensorer

Som vi nævnte før, vil vi bruge esp8266 til at læse og sende sensordata. I denne vejledning antager vi, at du ved, hvordan du tilslutter dine sensorer til din mikrocontroller. Du skal også allerede vide, hvordan du uploader kode til en esp8266.

Vores esp -model har kun en analog port, så vi valgte at modtage analoge oplysninger fra vores lyssensor, for så kan vi overvåge, hvor meget lys planten får.

Alle andre sensorer er forbundet digitalt. Vores DHT11 -sensor sender data digitalt, og vi bruger dht -biblioteket til at fortolke sensordata.

Ovenfor kan du finde et kredsløbsdiagram for de sensorer, vi brugte. Men husk, at de sensorer, vi brugte, ofte kommer med et modul, så du nemt kan slutte det til din mikrokontroller uden alle de ekstra modstande, som vi inkluderede i diagrammet.

Trin 2: Kode

Dette er den arduino -skitse, vi brugte. Du kan lære mere om, hvordan koden fungerer, hvis du læser kommentarerne.
