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
