Real-Time Sensor Data Aggregation across Remote Facilities for Centralized Cloud Analytics for Remote Sensor Data Aggregation Applications

Description

This use case implements a Remote Sensor Data Aggregation Application that collects sensor data from multiple remote facilities and centralizes it in the cloud. The application receives sensor readings, validates and aggregates the data, and transfers it to the cloud for centralized storage, real-time monitoring, and historical analytics.

Aim

To implement a real-time sensor data aggregation architecture that collects data from distributed remote facilities and provides centralized cloud-based analytics.

Objectives

01 Collect sensor data from multiple remote facilities.
02 Aggregate sensor readings in real time.
03 Validate and filter incoming sensor data.
04 Transfer aggregated data securely to the cloud.
05 Store sensor data centrally.
06 Provide real-time monitoring and analytics.
07 Support historical sensor-data analysis.
08 Scale data collection across multiple facilities.

Application Workflow

01

Stage 1 – Sensor Data Collection

Process

MQTT
Implementation

Python services receive sensor readings through MQTT from sensors and local gateways.

02

Stage 2 – Sensor Data Validation

Process

Validate incoming sensor data and identify invalid or missing readings.

Tools
PostgreSQL
Implementation
