PInt@t10n: Smart Plant Monitoring System: 9 stappe

2024 Outeur: John Day | [email protected]. Laas verander: 2024-01-30 07:26

Hierdie projek is geskep as 'n toets vir die ibm iot -wolk. Ons gebruik 'n esp-8266 om data van en na die ibm-wolk te stuur en te ontvang. Die kommunikasie tussen die esp en die ibm -wolk geskied deur middel van MQTT.

Ons gebruik node-rooi om al die data te hanteer en om 'n gebruikerskoppelvlak aan die gebruiker voor te stel. Dit is baie beginner vriendelik.

Om aan die gang te kom, benodig u:

• Esp-8266
• dht 11/22 temp/vog sensor
• Fotosensitiewe diode (ligmeting)
• gonser
• grondvog sensor
• ibm -wolkrekening

Stap 1: Koppel u sensors

Soos ons vroeër genoem het, gaan ons die esp8266 gebruik om sensordata te lees en te stuur. Vir hierdie tutoriaal gaan ons aan dat u weet hoe u u sensors aan u mikrobeheerder moet koppel. U moet ook reeds weet hoe u kode na 'n esp8266 moet oplaai.

Ons esp -model het slegs een analoog poort, so ons het gekies om analoog inligting van ons ligsensor te ontvang, want dan kan ons monitor hoeveel lig die plant kry.

Alle ander sensors is digitaal gekoppel. Ons DHT11 -sensor stuur data digitaal en ons gebruik die dht -biblioteek om die sensorsdata te interpreteer.

Hierbo kan u 'n stroombaan -diagram vind vir die sensors wat ons gebruik het. Hou egter in gedagte dat die sensors wat ons gebruik het gereeld 'n module bevat, sodat u dit maklik aan u mikrobeheerder kan koppel sonder al die ekstra weerstande wat ons in die diagram bevat.

Stap 2: Kode

Dit is die arduino -skets wat ons gebruik het. U kan leer hoe die kode werk as u die opmerkings lees.
