Project: Firebase Real-time Database for IoT Applications

System Diagram

NodeMCU with a BME280 sensor

1. install Firebase Arduino Client library for ESP32 and ESP8266 in Arduino IDE
2. download example code firebase_client.ino and run the code (make sure you modify the WiFi and API key/Database URL configs at the top of the program)

Raspberry Pi with a BME280 sensor

1. install firebase-admin package for Python: pip install firebase-admin
2. code firebase_test.py: Test if it can write/read data to/from firebase
3. code firebase_bme280.py: push sensor data along with the date/time information to the firebase.
4. code savedata.py: called by firebase_bme280.py to save data locally on Raspberry pi.
