This level of specificity enables precise monitoring and analysis of environmental conditions across the warehouse, facilitating the identification of particular areas or times when temperatures may have strayed from the norm.
  ‍
• Sensor Data Analysis: This segment provides day-wise summaries of the minimum, maximum, and average temperatures for all temporary sensors. Through analyzing these metrics, users can uncover patterns and trends that may signal systemic issues or areas necessitating additional monitoring.
  ‍
• Timeline Visualization: The visual representation of temperature data over time empowers users to observe trends and evaluate whether all readings fall within specified action and alert thresholds. This visual aid is especially beneficial for promptly detecting anomalies or periods of instability that may warrant further scrutiny.

• Deviation Graph: The deviation graph compares data from fixed and temporary sensors to ensure uniformity across various monitoring points. It flags any discrepancies exceeding 2°C lasting over two hours between fixed and temporary sensors, yielding a clear pass/fail outcome. This KPI is fundamental for validating sensor precision and guaranteeing that all sensors furnish dependable data meeting validation criteria.
  ‍
• Logger Comparison & Accuracy Testing: A T-test was conducted to evaluate the precision of fixed and temporary dataloggers. The null hypothesis posited no notable distinction in temperature readings between the two types of loggers, whereas the alternative hypothesis suggested a variance in their measurements. Rejection of the null hypothesis occurs when the P-value is below 0.05, indicating that there is no disparity in the data obtained from temporary and fixed dataloggers. This implies that the accuracy of temporary and fixed dataloggers is equivalent.

By leveraging these features, businesses can maintain precise environmental control, reduce risks, and ensure that their warehouse operations align with industry regulations and best practices.

3.2. Fixed Sensors Dashboard
