ES105M
  1.  Outdoor Multiple Air Sensor TVOC CH2O O3 O2 H2S CH4 CO NO2 SO2 H2 NH3

The ES105M series is an intergraded outdoor sensor unit for multiple gas sensors. The monitored data is output through RS-485 interface by Modbus protocol. The ES105M sensor unit accepts 10~30Vdc power input voltage and is protected by the IP65 grade Anti-U/V lightweight ABS louver radiation shield. With the optional NBIoT/WiFi gateway WR222 or LoRa end node LC144, the data can be monitor on the cloud platform.

Intergraded Device
  • Intergraded multiple sensorsCentral management by sharing a signal output
  • Support Industrial Modbus RTU protocol, RS485
Outdoor Protective Enclosure
  • 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
Flexible Design
  • Customized Shutter Height: Single or multiple parameters both can use small shutter, small size, light weight and easy to install
  • Customized Monitoring parameters: Each parameter is independent and high sensitivity, users can freely integrate monitoring parameters
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
