Today iam going to show you how to esp8266 datalogger With Different Sensors this is a simple project does not require high knowledge about arduino and electronics this is an intermediate level project, so its kind of okay to you. I tried my best to document this project to you, to look simple. so you can also make this project as I do, if you appreciate my work, a sub to my youtube channel will make me happy and keeps me motivated so I can make new projects for you in the near future, so with out further ado lets get started........

EXPANDED TECHNICAL DETAILS

Persistent Environmental Analytics

This project creates a robust, standalone data logger capable of recording thousands of sensor readings over weeks of operation.

  • FAT32 File System Hub: Uses the SD.h library to manage a standard microSD card. The Arduino captures data from DHT11 (Temp/Hum) and LDR (Light) sensors, packing them into a structured .CSV file.
  • Power Failure Resilience: Includes a "Flush" command after every 10 logs, ensuring that data is physically written to the card even if the battery dies unexpectedly.

Dashboard Features

  • Serial Real-Time Mirror: Simultaneously streams the data to the Serial monitor for live debugging while the main log is written to the SD card.
