Outdoor SO₂ Sensor – ES101SO2-2000
Sulphur dioxide (SO₂) is one of the key air pollutants that directly affects urban air quality, industrial emissions, and public health.
Accurate and continuous monitoring of SO₂ is essential for both Smart City environmental systems and Smart Factory emission control.
The ES101SO2-2000 is designed as a reliable outdoor sensing technology that enables real-time detection of SO₂ concentration across city environments and industrial facilities.
Smart City Applications
In Smart City deployments, SO₂ monitoring plays a critical role in:
- City-wide air quality monitoring networks
- Industrial zone and power plant perimeter monitoring
- Environmental compliance and pollution reporting
- Public health protection and early-warning systems
ES101SO2-2000 supports continuous data collection and centralized visualization, allowing city operators to analyze pollution trends and respond quickly to abnormal events.
Smart Factory Applications
In Smart Factory environments, SO₂ emissions are commonly found in:
- Boilers and combustion processes
- Chemical and petrochemical plants
- Metal processing and refining facilities
- Energy and utility operations
The sensor enables factories to monitor emission levels in real time, improve worker safety, and support automated environmental control systems.
