PInt@t10n: Smart Plant Monitoring System: 9 trinn

Dette prosjektet ble opprettet som en test for ibm iot -skyen. Vi bruker en esp-8266 til å sende og motta data til og fra ibm-skyen. Kommunikasjonen mellom esp og ibm -skyen skjer gjennom MQTT.

For å håndtere alle dataene og for å presentere brukeren et brukergrensesnitt bruker vi node-rødt. Det er veldig nybegynnervennlig.

For å komme i gang trenger du:

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

Trinn 1: Koble til sensorene

Som vi nevnte før, skal vi bruke esp8266 til å lese og sende sensordata. I denne opplæringen antar vi at du vet hvordan du kobler sensorene til mikrokontrolleren. Du må også allerede vite hvordan du laster opp kode til en esp8266.

Vår esp -modell har bare en analog port, så vi valgte å motta analog informasjon fra lyssensoren vår, for da kan vi overvåke hvor mye lys planten får.

Alle andre sensorer er koblet digitalt. Vår DHT11 -sensor sender data digitalt, og vi bruker dht -biblioteket til å tolke sensordata.

Over finner du et kretsdiagram for sensorene vi brukte. Men vær oppmerksom på at sensorene vi brukte ofte kommer med en modul, slik at du enkelt kan koble den til mikrokontrolleren din uten alle de ekstra motstandene som vi inkluderte i diagrammet.

Trinn 2: Kode

Dette er arduino -skissen vi brukte. Du kan lære om hvordan koden fungerer hvis du leser kommentarene.
