@salmanfaris OBD devices are in every new cars right, I don't know if I am right but I think we need seperate android app to collect data using obd and i think it don't retrive accelerometer reading i guess.

Hi @Abhay ,

Yes, OBD interfaces are now available in most the cars these days , you can get the vehicle sensor data using the OBD interface and you can process it using any controller like esp8266 or something.

Car => Data => OBD => Micorcontroller

@salmanfaris don't we need seperate android apps for collecting those data.?

@Abhay As you mentioned, I strongly feel that, the infotainment systems inside the cars these days aren't serving data like GPS location and all. I have used the OBD(On-Board Diagnostics) module in order to acquire data like Fuel tank levels, acceleration of the car, Brake levels, Battery levels, etc., In order to acquire the data like GPS you can install your own GPS module like UBLOX GPS sensor which can be easily interfaced over UART of any MCU's like ESP8266, ESP32, Arduino etc., and pertaining to your last question in the thread I would say "NO" you don't need any separate android apps to obtain data from OBD devices(if they are Bluetooth enabled). Because OBD's like ELM327 is Bluetooth enabled and hence you can use a simple Bluetooth terminal app to connect and get the data.
