ES101NO2 Outdoor Nitrogen Dioxide NO2 Sensor

ES101NO2 is an Outdoor Nitrogen Dioxide NO2 Sensor for air quality monitoring.

Outdoor Protective Design

• Prevent direct ultraviolet radiation to the sensors
• Avoid rapid aging of sensors under harsh environmental conditions such as strong winds, rain, and snow
• The sensor parts are ventilated for truly sensing the changes in external detection parameters
• Single or multiple parameters both can use small shutter, small size, lightweight and easy to install

Optional IoT Router and Cloud Platform - ThingsMaster

• Support Modbus to connect optional NBIoT Gateway WR222 for one or many sensors
• Real-time online monitoring, analysis, reporting
• Remote cloud security and visual management
