Latest commit 30f1cf4 Jan 6, 2017 @stanleyhuangyc Saved some SRAM

This sketch turns a Freematics ONE device into a wireless (WIFI) vehicle data collector and transmitter. The live data of a car, including OBD-II, GPS and MEMS sensor data, is collected in realtime, cached in SRAM and pushed to a HTTP server by HTTP POST continuously.


  • Freematics ONE with ESP8266 WIFI module -
  • Arduino IDE (for compiling and uploading the code)
  • A Freematics Hub server key
  • A wireless AP or hotspot with known SSID and password
  • A car with OBD-II port
