ESP8266 Temperature Sensor Firebase

This projects demonstrates reading data from a temperature sensor and sending in to Firebase for real-time monitoring.

Getting Started

This project uses the open source PlatformIO IDE built on top of Microsoft's Visual Studio Code.

Prerequisites

• NodeMCU ESP8266
• DS18B20 Temperature sensor
• Breadboard and jumper wires
• A computer with PlatformIO IDE installed

In addition to the hardware requirements, you also need to setup a Firebase Realtime Database, with Anonymous User Authentication enabled.

Installation

1. Clone this repository to your local machine.
2. Open the project in PlatformIO IDE.
3. Install the necessary libraries mentioned in the platformio.ini file.
4. Copy the ./src/secrets.h.example to a ./src/secrets.h file and update it.

Running the Project

1. Connect the temperature sensor to the board as per the circuit diagram provided.
2. Connect the board to your computer.
3. Upload the code to the board using the PlatformIO IDE.
4. Open the serial monitor to view the temperature data as it's being sent.
