Minimal DHT sensor Csv logger

Simple. Read a DHT sensor and write log collected data to a SD card.

I'm sure that if you are newbie you can learn a lot on this project!

Features

Mount a SD card
Read a DHT sensor (temperature + relative humidity + calculated heat index)
Uses the time of compilation (time of writing to device) as start time for the program. A upgrade should be call the internet for getting time from an API or adding a hardware clock
Writes to a log file which rotates every day
Good practices such as build configurations, time and manipulation, documentation, etc
Using the board built in led to give user feedback (when SD is being used)

It has been built on PlatformIO and ESP8266, it should compatible with any board using arduino.

📂 Clone or download.
📝 Add project to PlatformIO (it's a VSCode or Atom extension).
📝 Configure your board and platform on platformio.ini (all configurations, if neccesary create new project from ui and copy from it).
📝 Configure constants on top of main.cpp
☑️ Select the env:debug configuration.
🚀 Hit build, upload and monitor.
✨ Watch the serial output or checkout the sdcard after a while.

If you have any question about something specific, open an issue (but i won't be a teacher).
