How to create a smart dashboard that tracks industrial emissions in real time using IoT technologies
Industrial monitoring systems are becoming more advanced every year.
Factories, transport systems, and industrial plants now need continuous visibility into:
Air pollution levels
Gas emissions
Temperature conditions
Environmental compliance metrics
Traditional monitoring methods are often slow and manual.
That creates problems like:
❌ Delayed alerts
❌ Inaccurate reporting
❌ Poor operational visibility
❌ Compliance risks
This is why industries are adopting IoT-based real-time emission monitoring dashboards.
These systems combine:
Sensors
IoT devices
Cloud platforms
APIs
Live dashboards
to provide instant environmental insights.
In this article, we’ll explore how to build a real-time emission monitoring dashboard using IoT technologies and modern web architectures.
🚀 Why Real-Time Emission Monitoring Matters
Industrial emissions can change rapidly.
Without real-time monitoring:
Pollution spikes may go unnoticed
Equipment failures may remain undetected
Environmental violations may occur
Real-time dashboards help organizations:
✅ Monitor emissions continuously
✅ Detect threshold breaches instantly
✅ Improve environmental compliance
✅ Make faster operational decisions
👉 Visibility leads to faster action.
🧠 What Is an IoT Emission Monitoring Dashboard?
An IoT emission monitoring dashboard is a system that:
Collects environmental data from sensors
Sends data to cloud infrastructure
Processes events in real time
Displays live insights visually
The dashboard becomes the central interface for monitoring environmental conditions.
🧩 Core Components of the System
Let’s break the architecture into layers.
1️⃣ Sensor Layer 📡
Sensors collect environmental data continuously.
Common sensors include:
CO₂ sensors
Air quality sensors
Temperature sensors
Humidity sensors
Smoke detection sensors
Example data:
{
"co2": 420,
"temperature": 31,
"humidity": 58
}
👉 Sensors generate the raw environmental information.
2️⃣ IoT Device Layer ⚡
IoT devices process and transmit sensor readings.
Popular hardware:
ESP32
Arduino
Raspberry Pi
Responsibilities:
Read sensor values
Filter noisy data
Send data to APIs or MQTT brokers
Example:
int sensorValue = analogRead(A0);
👉 Devices act as the bridge between sensors and cloud systems.
3️⃣ Communication Layer 🌐
Sensor data must move reliably to backend systems.
Common protocols:
MQTT
HTTP APIs
WebSockets
MQTT is especially popular because it is:
Lightweight
Fast
Designed for IoT environments
👉 Communication efficiency is critical for real-time systems.
4️⃣ Cloud Backend Layer ☁️
The cloud handles:
Data storage
Real-time processing
Analytics
Alert systems
Popular cloud platforms:
AWS
Azure
Google Cloud
Backend technologies:
Node.js
Python
Express.js
👉 The cloud powers scalability and centralized monitoring.
5️⃣ Database Layer 🗄️
Environmental systems generate time-series data.
Common databases:
InfluxDB
PostgreSQL
MongoDB
The database stores:
Historical emissions
Alert history
Sensor logs
👉 Historical data helps with reporting and analysis.
6️⃣ Real-Time Processing Layer 🔄
Real-time systems need immediate event handling.
Tasks include:
Threshold monitoring
Alert generation
Event streaming
Analytics calculations
Technologies:
Kafka
RabbitMQ
WebSocket servers
👉 Real-time processing keeps dashboards live and responsive.
7️⃣ Dashboard Frontend Layer 📊
This is the user-facing part of the system.
The dashboard displays:
Live sensor readings
Emission charts
Alert notifications
Historical trends
Frontend technologies:
React
Vue.js
Chart.js
Grafana
👉 Visualization makes environmental data easier to understand.
⚡ Building the Dashboard Step by Step
Step 1: Collect Sensor Data
Sensors continuously capture environmental conditions.
Example:
const sensorData = {
co2: 450,
temperature: 30
};
Step 2: Send Data to Backend APIs
IoT devices transmit data to the server.
Example:
fetch('/api/emissions', {
method: 'POST',
body: JSON.stringify(sensorData)
});
👉 APIs become the communication bridge.
Step 3: Store Data in Database
Incoming data is saved for analytics and reporting.
Example database fields:
Timestamp
Sensor ID
CO₂ level
Temperature
👉 Time-series storage improves monitoring efficiency.
Step 4: Process Real-Time Events
Backend systems analyze incoming data instantly.
Example:
if (co2 > 1000) {
triggerAlert();
}
👉 Immediate alerts improve operational response.
Step 5: Display Data on Dashboard
Frontend dashboards fetch live updates using WebSockets or APIs.
Features include:
Live charts
Gauge indicators
Alert banners
Historical analytics
👉 Operators gain real-time visibility.
🚨 Real-Time Alert Systems
One major advantage of IoT dashboards is instant alerting.
Alerts can notify users about:
High pollution levels
Sensor failures
Temperature breaches
Notifications may include:
SMS alerts
Email notifications
Mobile push alerts
👉 Fast alerts reduce environmental risks.
