Overview

       aMG 4-20mA to WiFi Data Logger is a device that can read up-to 4 channels of 4-20mA data every 1 second. The data can be encrypted and sent to a customer own database server securely via WiFi, with 7-years-worth of in-device backup storage (a micro SD card). Therefore, you will always have critical information, to the finest detail, stored securely and redundantly both in your own server and in the device.

     Installation and usage are simple. No need for data link cabling. No need to collect data on-the-spot. No need to worry about data security and privacy. Just setup your own database server, connect the device to a common WiFi network, and wait for the data to arrive in your database. Most suitable for customer with basic IT knowledge to set up your own database server (free example source code available for our customers).

Key features

  1. Concurrently record all data to internal storage and send data to your own remote database server.
  2. Support RESTful API webservice with time-varying user-customizable secret-keyed AES encrypted JSON data package.
  3. Free server setup source code example e.g., Php + MySQL and Node.js + SQLite.
  4. Easy setup via a web application, just like setting up any WiFi access point at home.
  5. User and role-based management for device access control by an administrative
  6. Circular buffer mechanism to ensure precise data acquisition timing.
  7. Configurable heartbeat service for data connection health checks.
  8. Over-the-Air firmware upgradable to take advantage of new features in the future.
  9. Included in package: 5 dB 2.4GHz omni-directional antenna and 16GB micro SD card
