Sir, my final year project is about vehicle vibration/accident detection. Here, I’m using Arduino Uno, Accelerometer ADXL335, GPS module Neo-6m, GSM SIM800. I’m going to mount this system on bike.
Which power source should I use for sim800? Datasheet i/p = 3.4 - 4.2v, 2A. I tried using 9v battery but its not working.
What you didnt understand from the video?
There is tutorial on Adafruit and cloudmqtt which show how data can be sent via GPRS to the servers.
Go through all of them. its a playlist.
Study SIM modules HTTP and TCP AT commands, then you will come to know how to send data, Demos are in the playlist i shared above.
