PInt@t10n: Pametni sistem za nadzor rastlin: 9 korakov

2024 Avtor: John Day | [email protected]. Nazadnje spremenjeno: 2024-01-30 12:05

Ta projekt je nastal kot test za oblak ibm iot. Za pošiljanje in sprejemanje podatkov v oblak ibm in iz njega uporabljamo esp-8266. Komunikacija med esp in oblakom ibm poteka prek MQTT.

Za obdelavo vseh podatkov in predstavitev uporabniku uporabniškega vmesnika uporabljamo node-red. Je zelo prijazen začetnikom.

Za začetek potrebujete:

• Esp-8266
• senzor temp./vlage dht 11/22
• fotoobčutljiva dioda (merjenje svetlobe)
• zvočni signal
• senzor vlažnosti tal
• ibm račun v oblaku

1. korak: Povežite svoje senzorje

Kot smo že omenili, bomo za branje in pošiljanje podatkov tipala uporabili esp8266. V tej vadnici bomo domnevali, da veste, kako povezati svoje senzorje z mikro krmilnikom. Prav tako morate že vedeti, kako naložiti kodo na esp8266.

Naš model esp ima samo ena analogna vrata, zato smo se odločili prejemati analogne informacije od našega svetlobnega senzorja, ker lahko potem spremljamo, koliko svetlobe rastlina dobi.

Vsi drugi senzorji so digitalno povezani. Naš senzor DHT11 podatke pošilja digitalno, za razlago podatkov senzorjev pa uporabljamo knjižnico dht.

Zgoraj najdete diagram vezja za senzorje, ki smo jih uporabili. Upoštevajte pa, da so senzorji, ki smo jih uporabljali, pogosto opremljeni z modulom, tako da ga lahko preprosto povežete z mikrokrmilnikom brez vseh dodatnih uporov, ki smo jih vključili v diagram.

2. korak: Koda

To je skica arduino, ki smo jo uporabili. O tem, kako deluje koda, lahko izveste, če preberete komentarje.
