The Rover Navigation Optimization System is a project by Tejas Gupta and Ojas Gupta developed under the guidance of Prof. Bindu Garg, HOD, CSE & CSBS, Bharati Vidyapeeth University, College of Engineering, Pune. It is a scaled-down prototype designed to explore real-time environmental monitoring and data-driven decision-making. The project focuses on collecting temperature and humidity readings to analyze climate conditions and detect anomalies that could impact autonomous navigation.

A scaled-down Rover prototype can effectively collect temperature and humidity data, demonstrating how real-time environmental monitoring can be used for autonomous navigation, climate analysis, and anomaly detection.
By analyzing the collected data, we aim to identify trends, evaluate sensor accuracy, and explore potential improvements in robotic exploration. This includes assessing response time, consistency, and anomalies caused by external factors like human interference or sudden environmental changes.

This dataset contains 5,400 timestamped temperature and humidity readings collected over a period of 3 hours and logged every 2 seconds by the rover’s onboard DHT22 sensor. The data highlights:
- Gradual fluctuations in environmental conditions.
- Notable temperature spikes
(~10°C)introduced using a lighter to test sensor response. - Stable humidity levels with minor deviations due to air circulation or sensor drift.
- Controlled Temperature Spikes: Short bursts of heat resulted in clear temperature increases
(~10°C), demonstrating the sensor's ability to detect and log transient changes. - Humidity Stability: Humidity levels remained within a narrow range, confirming minimal impact from applied temperature fluctuations.
- Gradual Environmental Variations: Small temperature and humidity shifts were observed, likely due to ambient conditions and ventilation effects.
- Sensor Used: DHT22 (for temperature & humidity).
- Data Collection Frequency: Logged every few seconds.
- Controlled Testing: Heat spikes added using a lighter to simulate external interference.
- Data Transmission: Logged in real-time via wireless communication to a laptop.
