Outdoor Carbon Monoxide (CO) Monitoring Technology is a critical safety technology within Service & Smart City environments, enabling continuous detection of toxic carbon monoxide levels in public and urban infrastructure. By providing real-time CO concentration data, this technology supports accident prevention, public health protection, and proactive environmental risk management.
The technology is powered by industrial-grade outdoor sensors such as the ES101CO Carbon Monoxide Sensor, designed for fast response, high accuracy, and stable operation in challenging outdoor environments.
Core Technology Capabilities
High-Resolution CO Detection for Safety Applications
The system supports a CO measuring range of 0–2000 ppm with 1 ppm resolution and measurement accuracy of ±3%, ensuring precise detection of low and high concentration levels in real time. With response times of ≤3 seconds, abnormal conditions can be identified immediately.
Stable Performance for Continuous Monitoring
Designed for 24/7 safety monitoring, the technology maintains long-term stability of ≤2% signal drift per month, providing reliable data for regulatory compliance and safety analytics without frequent recalibration.
Industrial Communication & System Integration
Equipped with RS-485 (2-wire) Modbus RTU communication, the technology integrates seamlessly with:
- Smart City safety platforms
- Environmental and air-quality monitoring systems
- SCADA, BMS, and PLC-based control systems
- Urban analytics and alarm management solutions
Standard register mapping allows simple configuration and data access.
Low Power & Robust Outdoor Design
With ultra-low power consumption (<0.18W) and wide operating voltage (10–30 VDC), the sensor is optimized for continuous outdoor deployment. The IP54-rated enclosure, flame-retardant ABS housing (UL94V0), and optional outdoor shelter ensure durability against dust, moisture, and environmental exposure.
IoT & Cloud-Enabled Expansion
When connected to an optional NB-IoT gateway, the technology enables:
- Real-time online monitoring and alerts
- Cloud-based data storage, analysis, and reporting
- Remote device and security management
- Scalable deployment of distributed sensor networks
This supports the evolution toward intelligent, connected urban safety systems.
