Mradi huu uliundwa kama jaribio la wingu la ibm iot. Tunatumia esp-8266 kutuma na kupokea data kwenda na kutoka kwa wingu la ibm. Mawasiliano kati ya esp na wingu la ibm hufanyika kupitia MQTT.

Kushughulikia data zote na kuwasilisha mtumiaji kiolesura cha mtumiaji tunatumia node-nyekundu. Ni rafiki wa Kompyuta.

Ili kuanza unahitaji:

• Esp-8266
• dht 11/22 temp / sensor ya unyevu
• diode ya kupendeza (kipimo nyepesi)
• buzzer
• sensorer ya unyevu wa ardhi
• akaunti ya wingu la ibm

Hatua ya 1: Unganisha Sensorer zako

Kama tulivyosema hapo awali tutatumia esp8266 kusoma na kutuma data ya sensorer. Kwa mafunzo haya tutadhani unajua jinsi ya kuunganisha sensorer zako kwa mdhibiti wako mdogo. Pia unahitaji kujua jinsi ya kupakia nambari kwa esp8266.

Mfano wetu wa esp una bandari moja ya analogi kwa hivyo tulichagua kupokea habari ya analog kutoka kwa sensa yetu ya taa kwa sababu basi tunaweza kufuatilia ni kiasi gani taa hupata.

Sensorer nyingine zote zimeunganishwa kidijitali. Sensorer yetu ya DHT11 hutuma data kwa dijiti na tunatumia maktaba ya dht kutafsiri data ya sensorer.

Hapo juu unaweza kupata mchoro wa mzunguko wa sensorer tulizotumia. Lakini tafadhali kumbuka kuwa sensorer tulizotumia mara nyingi huja na moduli ili uweze kuiunganisha kwa urahisi na mdhibiti wako mdogo bila vipinga vyote vya ziada ambavyo tulijumuisha kwenye mchoro.

Hatua ya 2: Kanuni

Huu ndio mchoro wa arduino tuliotumia. Unaweza kujifunza juu ya jinsi nambari inavyofanya kazi ikiwa utasoma maoni.
