Local weather station with BME280
- Student: Andreea Miu
- Master: SAS
Introduction
This project describes a local weather station, which is included in a larger Android application.
The purpose of this project is to provide a proof-of-concept for adding local weather stations to standard weather applications, in order to have a more granular approach on weather based on customizable location and measured data.
Hardware Setup
Components
- ESP32-DevKitC-V4 board
- BME280 environmental sensor
- Jumper wires
Schematics
In the above schematics, the following pins are connected:
- VCC of BME280 - 3v3 of ESP32
- GND of BME280 - GND of ESP32
- SCL/SCK of BME280 - IO22 / GPIO pin 22 of ESP32 (default GPIO pin for I2C SCL)
- SDI/SDA of BME280 - IO21 / GPIO pin 21 of ESP32 (default GPIO ppin for I2C SDA)
Software Setup
The local weather station will send data to a database, in order to facilitate access to retrieved data. For this project, a Firebase real-time database is used.
