ESP32-DHT11-Firebase

This project use ESP32 board geting temperature and humidity from sensor DHT11, this data send to Firebase

Requirements

Components

Is necessary have the following components:

• ESP32
• Sensor DHT11
• Micro USB Cable

Libraries

To use this project it is necessary to have the following components installed.

• ESP32 Board in IDE Arduino
• Library Adafruit/DHT-Sensor
• Library Adafruit Unified Sensor Driver
• Library taranais/NTPClient
• Firebase-ESP32 Library

Notes

DHT11

• Define u pin data connected.
• Define u type sensor (DHT11 for DHT11, DHT22 for DHT22-AM2302-AM2321, DHT21 for DHT21-AM2301)

#define DHTPIN 15
#define DHTTYPE DHT11

NTP

• Config u timezone (get timezone), this is config for UTC -4 (Summer time in Santiago, Chile).

// -3 = UTC - 3
const long gmtOffset_sec = -3 * 60 * 60;
...
timeClient.setTimeOffset(gmtOffset_sec);

Firebase

• Get your credentials Firebase
