EH-Terminal G2S

The EH-Terminal GS2 is a sensor terminal with Analog Devices SmartMesh IP which allows for an easy mesh network deployment just by turning on the power.

The sensor terminal has a built-in gas sensor capable of wirelessly sensing the total volatile organic compound (TVOC) as one of the atomospheric pollution environmental indexes. The sensor terminal is also equipped with a temperature/humidity sensor, light luminance sensor, and accelerometer.


  • Collects verious sensor data wirelessly through automatically healing mesh networks by connecting to the Analog Devices USB Network Manager DC227A attached to a PC or a gateway device.
  • Measures total volatile organic compound (TVOC), temperature, humidity, light luminance, and acceleration using the sensors onboard.
    • The VOCs released into the environment cause hazards to human health such as sick house syndrome
  • Capable of connecting to cloud using 3G or LTE Cat.4 cellular networks through the CandyPi Lite board and a gateway with the Candy Pi Lite+ module from Candy Line, Inc.

Network Connection

  • EH-Terminal-connectionsADI Stargazer network topologyBy connecting a host USB Network Manager DC2274A (Analog Devices) to a PC or Gateway, the terminal devices automatically form a mesh network and start collecting various sensor data.
  • Once configured, the mesh network is automatically optimized even if the wireless environment temporarily deteriorates thanks to the self-healing function.
  • When the wireless network environment is unstable, installing additional devices automatically adds more network paths, resulting in optimizing existing mesh networks and reducing the user burden related to installation.
