6 Continuous Ambient Air Quality Monitoring Stations | 5 Locations | 5 Air Quality Parameters
Aaxis Nano Technologies is establishing six Continuous Ambient Air Quality Monitoring Stations (CAAQMS) across five locations for Eastern Coalfields Limited (ECL), enabling continuous air-quality measurement, real-time data transmission and improved environmental visibility across its operational areas.
Monitoring Across ECL Locations
The network covers Bankola Area, Jhanjhra Area, Pandaveswar Area, SP Mines – Chitra and SB Area ECL .
Each station combines ambient air analysers, meteorological sensors, sampling systems, data acquisition and communication infrastructure to support continuous monitoring at the designated locations.
Integrated Air Quality Measurement
The CAAQMS units are designed to monitor SO₂, NO–NO₂–NOx, CO, PM₁₀ and PM₂.₅, using measurement technologies including UV fluorescence, chemiluminescence, NDIR and β-ray attenuation
Alongside pollutant measurement, the stations monitor wind speed, wind direction, ambient temperature, rainfall, relative humidity and solar radiation, providing meteorological information tocomplement air-quality observations.
Real-Time Data. Connected Visibility
A Data Acquisition System (DAS) supports real-time data logging, storage, validation, backup and remote access. Monitoring data is transmitted to the servers of CPCB, State Pollution Control Boards, CIL and the Ministry of Coal, supporting centralised access to environmental information.
The communication arrangement includes leased-line, broadband and GSM/Hotspot connectivity, supporting data transmission from the monitoring locations.
Supporting Long-Term Monitoring
The project scope includes calibration, preventive and corrective maintenance, critical spares, consumables and real-time data transmission. Calibration checks and quality documentation are carried out in accordance with specified US EPA methodologies and quality requirements
.
The project is backed by a 3-year Comprehensive Annual Maintenance Contract (CAMC) covering maintenance and required spares.
By connecting continuous air-quality measurement, meteorological monitoring, data acquisition and real-time communication, the network provides Eastern Coalfields Limited with a common framework for environmental data collection, monitoring and reporting across multiple operational locations.
