Upimaji wa Joto Kutumia Esp32 na Jukwaa la Thingsio.ai: Hatua 6

2024 Mwandishi: John Day | [email protected]. Mwisho uliobadilishwa: 2024-01-30 12:52

Katika mafunzo haya nitaelezea juu ya kupima joto katika mazingira kwa kutumia sensorer ya joto iliyojengwa katika bodi ya maendeleo ya esp32. esp32 ina sensorer nyingi zilizojengwa kama sensa ya ukumbi inayotumiwa kama sensorer ya ukaribu, sensor ya kugusa, sensorer ya joto. Katika mafunzo haya tutazungumzia juu ya sensorer ya joto.

Hatua ya 4: PATO:

Hapa kuna pato la maadili ya joto yaliyosomwa kutoka kwa sensorer.

Hatua ya 5: GRAPHS:

Uwakilishi wa picha ya maadili yaliyosomwa kutoka kwa sensorer ya joto la ndani.
