Story

Introduction:-

I developed an innovative project integrating a Raspberry Pi Pico W with an Adafruit Pico W to collect environmental data using a BME280 sensor. The sensor captures temperature, humidity, and pressure readings, which are then transmitted to the cloud for real-time monitoring and analysis. A compact 2x2 display by SB Components is incorporated into the setup to locally visualize data in an intuitive manner. This project demonstrates an efficient IoT solution for environmental sensing, combining cutting-edge microcontroller technology with cloud connectivity for enhanced data accessibility and usability.

am also storing those data in sd card in csv format so make sure you have sd card.

SOFTWARE SETUP:

STEP 1 : Firmware Setup:

To develop the firmware for the above setup, follow the given steps:

Connect the Raspberry pi pico to the PC using Micro-A USB.
Download and install Thonny IDE from the official site.
Ensure that you have installed micropython Boot firmware which given in sb component website.If not thenhere is link of firmware given link.

STEP 2 : SELECT “Micropython ( Raspberry Pi Pico) Board CDC@

COM8

STEP 3: download and import sdcard.py and bme.py liberary from given link.

STEP 4:- now copy paste give application code.

STEP 5: Go to Adafruit website and signup or Login there.

STEP 6: click on feed >New feed.

STEP 7: after creating feed go to "Dashboard" and create dashboard.

STEP 8: copy adafruit username and adafruit key from right uppercorner key sign.

STEP 9 : now add import information in apllication code
