 # RasPi_terra
-Python and R code for temperature and humidity tracking using a Raspberry Pi.
+
+RasPi_terra is a tool for monitoring and controlling environmental conditions in terrariums using a Raspberry Pi. This repository contains the code for:
+
+1. Reading temperature and humidity data from multiple DHT22 sensors.
+2. Automatically controlling a fan based on predefined thresholds.
+3. Visualizing the data on an interactive dashboard created with R and Shiny.
+
+---
+
+## Features
+
+- **Sensor Monitoring**: Continuously reads temperature and humidity data from up to four DHT22 sensors.
+- **Fan Control**: Automatically manages fan operation based on monthly temperature thresholds.
+- **Interactive Dashboard**: Displays real-time and historical data trends in an R Shiny application with multiple tabs for detailed analysis.
+
+---
+
+## Setup Instructions
+
+### Hardware Requirements
+
+- Raspberry Pi with GPIO pins.
+- Up to four DHT22 sensors. (easily expandable with additional code)
+- A fan connected to a GPIO pin.
+- Required libraries installed on the Raspberry Pi (`Adafruit_DHT`, `gpiozero`, etc.).
+
+### Software Prerequisites
+
+1. Install Python 3 and required Python libraries:
+   ```bash
+   pip3 install Adafruit_DHT gpiozero
+2. R with following packages: shiny, shinyWidgets, stringr, lubridate, dplyr, ggplot2.
+3. Command line software such as "Ubuntu for windows" to run the .sh wrapper script.
