Environmental Monitoring System

Smart Industrial Environmental Monitoring System

Real-Time Industrial Environmental Monitoring & IoT Platform

Silentronics designed and developed a connected industrial environmental monitoring system for continuously measuring critical workplace and facility parameters. The solution combines an industrial edge device, internal environmental sensing, LTE/Wi-Fi connectivity, cloud monitoring, alerts, analytics, and mobile access into a single end-to-end IoT platform.

The system is designed for industrial environments where continuous visibility of temperature, humidity, air quality, particulate matter, VOCs, atmospheric pressure, noise, and lighting conditions is required.

☞ System Architecture

The solution follows an end-to-end architecture:

Environmental Sensors → Edge Device → LTE/Wi-Fi Connectivity → Cloud Platform → Web Dashboard & Mobile Application

The edge device collects sensor data locally, performs processing and limit checking, and securely transfers the data to the cloud for storage, analytics, visualization, and alert generation.

☞ Hardware Development

The hardware was designed around an industrial edge-computing architecture capable of collecting multiple environmental parameters while providing reliable connectivity to cloud infrastructure.
