Downlod Specification In PDF
System Feature
Wi-Fi/Ethernet Connected
- Connection is from device connected to server.
- Once system power up, it will auto create a persistence connection to the server without user intervention.
- Server can be placed either at public cloud, private cloud or LAN.
- Device able to work behind firewall.
Network link with MQTT Broker Server
- Open Standard protocol and readily available either using paid version or free version of MQTT Broker.
- Messaging format based on JSON format.
- JSON messaging format is supported by various programming language and easily integrated to any existing system.
- Device support Secure WebSocket or Secure TCP connection to MQTT Broker.
Direct link with USB Connection
- The device also can be configured to use USB Connection without connecting to the network.
- Suitable for direct connection with PC/Host system locate beside the device.
- Just add an extra JSON layer of wrapper to wrap around the same JSON messaging standard used in the MQTT Broker Server communication.
- Thus provide an easy path for future system expansion, from localized system architecture to network-based system architecture.
Device’s sensors with MEMS
- Build in with Micro-electromechanical systems sensors (MEMS) technology
- Highly accurate and fully digital output direct from the sensors.
- Sensors are calibrated and accuracy are guarantee by sensor manufacturer.
TFT display
- Colorful TFT display design
- Eye-caching of the sensor reading from a far.
Auto fetch real time clock from Internet Time Server.
- Auto connect with the Internet Time Server to fetch the Real time value (EPOC Time) when network is connected and internet link is available.
- Manually set time by server if internet link is not available.
- Auto readjust the time drift periodically.
- Append the EPOC time to all the message.
Easy setup and configuration
- System configures with Android Apps.
- Provide detail device properties, E.g., model number, version number, etc.
- Connectivity selection either using Wi-Fi, Ethernet or USB Link.
- Upload WPA Enterprise Server private/public key.
- Server IP/Domain Name Setup.
- DHCP/Fix IP.
- Internet Time Server Setting.
