Upimaji wa Maudhui ya Unyevu wa Udongo 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 usomaji wa unyevu kwenye mchanga kwa kutumia esp32 na kisha kutuma maadili kwenye jukwaa la wingu la thingsio.ai IoT.

Hatua ya 1: VIFAA

Vipengele vya vifaa:

1. esp32 bodi ya maendeleo

2. Sensorer ya mchanga

3. waya za Jumper

Programu:

1. Arduino IDE

2. Thingsio.ai

Hatua ya 2: Uunganisho

Sensorer ya Unyevu wa Udongo ---------------------- Bodi ya esp32

VCC ----------------------------------- 3V3

GND -------------------------------------- GND

A0 ---------------------------------------- VP

Hatua ya 3: CODING:

Hatua ya 4: PATO:

Pato la nambari linaonyeshwa.

Hatua ya 5: GRAPH

Huu ndio uwakilishi wa picha ambazo zinasomwa kutoka kwa sensa.

Hatua ya 6:

Hapa kuna video kamili ya mradi huo. Asante.
