Environment Displays

AQI, PM2.5, PM10, temperature, humidity, SO₂ and noise — live data from your analyser, displayed on a high-brightness outdoor LED panel.

CPCB-compliant. Direct analyser interface. No intermediate PC. Built for 24×7 continuous outdoor operation.

Parameters we display

What goes on the screen

AQI Index
0–500, colour-coded Good / Moderate / Poor / Hazardous per CPCB scale
PM 2.5
µg/m³ — fine particulate matter, real-time
PM 10
µg/m³ — coarse particulate matter, real-time
Temperature
°C, ±0.3° accuracy
Relative Humidity
% RH, real-time
SO₂
µg/m³ — sulphur dioxide, stack and ambient
Noise Level
dB(A) — Leq, L90, peak, as required
NOx / CO₂
ppm — on request, for CEMS installations

Colour thresholds pre-programmed per CPCB guidelines. Any combination of parameters — scrolling, static or alternating — configured at our facility before dispatch.

Data interface

How data gets to the display

We support every standard connection method. Your existing analyser connects as-is — no proprietary hardware, no lock-in.

🔌
Direct from analyser

RS232, RS485 or Modbus RTU/TCP from your CEMS analyser. Real-time, no PC required. Zero latency between measurement and display.

🌐
Ethernet / TCP-IP

Display pulls data from a SCADA system or data logger over LAN or internet. Supports multiple displays from one data source simultaneously.

📄
PC log file reader

If your analyser software writes to a CSV or text log file, our software reads it continuously and updates the display. Works with CPCB-standard data loggers.

🔧
CSPL in-house sensor

We manufacture our own AQI, PM2.5, PM10, temperature and humidity sensors — pre-wired and configured with the display. One cable, one power supply.

📡
4–20 mA / Analog

Analog 4–20 mA or 0–10V from existing sensors. Controller converts to engineering units and displays on screen. No additional hardware.

☁️
API / Cloud feed

Pull from a cloud dashboard or government portal via REST API. Display updates over WiFi or SIM. Suitable for remote sites without wired connectivity.

Regulatory compliance

CPCB-compatible display systems

The Central Pollution Control Board mandates that industries above a specified threshold must display real-time stack emission and ambient air quality data publicly — without delay, manipulation or tampering.

Our displays meet these requirements: direct feed from the CEMS analyser, sealed controller enclosure, and tamper-evident wiring. We have supplied CPCB-compliant displays to industries across West Bengal.

🔒
Tamper-evident

Controller sealed. Data goes directly from analyser to display — no editable intermediate.

Real-time always

Updates within seconds of measurement. No buffering. Auto-restart on power failure.

📋
All CPCB parameters

PM2.5, PM10, SO₂, NOx, CO, O₃ and AQI — colour-coded per CPCB scale.

🏭
Industry-rated

IP65 enclosure, rated for Indian climate — heat, monsoon and dust. 24×7 continuous.
