Regulatory Compliance

CPCB compliance for pollution data display

Our boards meet the requirements of the Central Pollution Control Board for real-time public display of environmental data at industrial premises and public areas.

Our Pollution Parameter Display Boards are fully compliant with the Central Pollution Control Board (CPCB) Guidelines, Section 17 and 18 (Air Act 1981 and Water Act 1974). These boards ensure real-time display of critical pollution parameters:

Air Quality Index

PM2.5, PM10, SO₂, NOₓ, CO, Ozone, and AQI composite index

Water Quality

pH levels, dissolved oxygen (DO), biological oxygen demand (BOD), temperature

Noise Levels

Real-time noise pollution monitoring data where applicable under CPCB norms

The boards integrate with monitoring equipment via Modbus, APIs, or databases, ensuring accurate and reliable data dissemination. They comply with the CPCB's requirement for high-visibility displays at industrial premises and public areas.

Stay Compliant. Stay Transparent.

Every feature chosen for pollution monitoring

All required parameters

PM2.5, PM10, SO₂, NOₓ, CO, CO₂, Ozone, and AQI index — all configurable on a single board. Parameter layout matches CPCB display format requirements.

CAAQMS direct connection

Connects directly to CAAQMS data loggers via RS485, Modbus, or network interface. No manual data entry — live feed updates the display automatically.

AQI colour coding

Automatic colour change — green (Good), yellow (Satisfactory), orange (Moderate), red (Poor), maroon (Very Poor), dark maroon (Severe). Matches CPCB AQI colour index.

Daylight readable

6000–8000 nit outdoor brightness. Clearly readable in direct afternoon sunlight. IP65 rated — monsoon-proof enclosure with anti-corrosion treatment.

Buyer's Guide

How to select the right LED display

Six factors that determine which board is right for your site. Answer these before requesting a quote and we can turn around a proposal in 24 hours.

Location

Decide if the display is indoor, outdoor, or semi-outdoor. This drives brightness (nit), IP rating, and cabinet construction. Outdoor needs 6000+ nit and IP65. Indoor can be lower brightness with finer pitch.

Viewing distance

Pixel pitch in mm ≈ minimum comfortable viewing distance in metres. P4 looks crisp from 4 m away. For close-range viewing (under 3 m), choose P2.5 or finer. For long-range outdoor, P6–P10 is sufficient and more cost-effective.

Wall size & structure

Our standard cabinet is 960 × 960 mm. Final wall size should be a multiple of this. We provide structural drawings, mounting hardware, and civil drawings for all installation types — wall-mounted, freestanding, or suspended.

Content type

Static text and parameter values need a simpler controller. Full video requires higher bandwidth. Real-time industrial data (SCADA, PLC, 4–20 mA) needs our industrial display controller with native signal input — no PC required.

Maintenance & support

Ask about AMC (annual maintenance contracts), spare parts availability, and on-site response time. Our 3-year warranty covers parts and labour. AMC available after warranty period with guaranteed response within 48 hours.
