micropython_datalogger_esp8266

A simple MicroPython script for data logging environmental sensors on ESP8266 board with OLED data display. Libs used in this project are freezed(.mpy), using mpy-cross. Original source file is also included, checkout driver-libs directory. Libs under this directory can be changed and recompiled to suit your needs but it's seldom required unless you know what you are doing. Happy Hacking!!

** This project follows SemVer-v2.0.0 guidelines for it's new releases/tags.

Sensor Inputs:

• Bosch's BME280 in I2C mode.
• Maxim's DS18B29 in One Wire mode.
• Sensirion's SCD30 in I2C mode.

Outputs:

• Serial terminal debugging logs.
• SSD1306 White OLED Display in I2C mode.
• SD card logs using SD card module in SPI mode.
• Logging using Zapier workflow (zap) Integrating zapier webhook with Google sheets.

Dev console config:

• OS: Linux x64 5.10.0-1055-oem
• VS Code Version: 1.63.2
• VS Code Extension: Pymakr v1.1.17

Hardware Config:

• ESP8266 Node MCU V1.0 with Silicon Labs CP2102 UART to USB converter.
• MicroPython Firmware v1.18

Expected New Features:

• Setting up Huginn a hackable and opensource alternative to IFTTT and Zapier. (For those who want their own service running.)
• Hotswappable sensors.
• Key-pad -> Adding ssid and password on the go.
• Key-pad -> Screen scrolling and menu navigation.
