Outdoor CO₂ Monitoring Technology is an essential component of Service & Smart City ecosystems, enabling cities and organizations to monitor air quality, manage environmental risks, and improve public health through real-time data.
This technology utilizes industrial-grade outdoor sensors such as the ES101 CO₂ Carbon Dioxide Sensor, designed to accurately measure carbon dioxide concentrations in highly polluted and outdoor environments. The collected data supports air-quality assessment, urban environment analysis, and smart environmental decision-making.
Core Technology Capabilities
Wide-Range CO₂ Measurement for Urban Environments
The technology supports a wide CO₂ measuring range of 0–5000 ppm, with high accuracy of ±40 ppm + 3% FS (at 25°C). This makes it suitable for deployment in areas with heavy air pollution, high traffic density, and dense urban infrastructure.
Robust Outdoor Design & Protection
Built with a durable IP54-rated enclosure, flame-retardant ABS plastic (UL94V0), and optional outdoor shelter, the system ensures reliable performance against dust, moisture, and environmental stressors in outdoor installations.
Standard Industrial Communication
Supporting RS-485 (2-wire) communication with Modbus RTU protocol, the technology enables seamless integration with:
- Smart City platforms
- Environmental monitoring systems
- SCADA and BMS
- Urban data analytics platforms
Standard register mapping ensures compatibility with PLCs and industrial control systems.
Low Power Consumption & Long-Term Stability
With power consumption below 0.4W and long-term stability of <2% signal drift per year, the system is optimized for continuous outdoor operation with minimal maintenance requirements.
IoT & Cloud-Ready Architecture
The technology can be expanded using optional NB-IoT gateways, enabling:
- Real-time remote monitoring
- Cloud-based data analysis and reporting
- Secure visualization and centralized management
- Scalable deployment for city-wide sensor networks
This architecture supports the transition from standalone monitoring to fully connected smart environmental platforms.
Supporting Service & Smart City Applications
- Outdoor air quality monitoring
- Urban pollution assessment
- Smart transportation environments
- Public space and smart infrastructure monitoring
- Environmental compliance and sustainability programs
