⚙️ Time Sampling Data Logger UI with Teensy 4.1

This project is a real-time time-sampling and data logging system using Teensy 4.1 and multiple sensors. It provides a Streamlit-based User Interface (UI) to visualize sensor readings, record data at fixed intervals, and download the collected dataset as a CSV file.

🧠 Project Overview

The system continuously collects data from various environmental sensors connected to the Teensy 4.1 microcontroller, samples them at fixed intervals, and stores the readings for analysis. The Streamlit UI displays the time-sampled data and allows users to download the readings in .csv format for further processing or visualization.

🧩 Hardware Components Used

Component	Description	Function
Teensy 4.1	High-performance ARM Cortex-M7 microcontroller (600 MHz)	Central controller for reading and processing sensor data
TSYS01 Sensor	Temperature and pressure sensor (I²C)	Measures accurate temperature and pressure data
Pressure Sensor (Optional - if additional used)	Analog or digital pressure sensor	Measures depth or pressure changes
SD Card Module	SPI-based storage module	Logs sampled sensor data locally on the SD card
RTC Module (Real Time Clock)	Built-in or external	Provides accurate timestamps for each sampled data point
Power Source (USB / External 5V)	-	Powers the Teensy and all connected peripherals

🧠 Software & Tools

1.Programming Language: Python 3

2.Microcontroller Platform: Teensy 4.1 (Arduino IDE)

3.UI Framework: Streamlit

4.Data Handling: Pandas

5.Data Format: CSV

⚙️ Working Principle

Teensy 4.1 collects data from all sensors via I²C/SPI.

Each reading includes: 1.!Timestamp (from RTC)

2.Temperature (from TSYS01)

3.Pressure (from TSYS01 or external sensor)

4.The data is sent via Serial or stored on the SD card.

5.The Streamlit UI reads the incoming data stream or file, displays it, and allows export to CSV.
