Accelerometer Hardware connection with Arduino:
Arduino -----Accelerometer
5v ----- Vcc
GND ----- GND
A0 ----- X-axis (Xout)

NodeMCU required a code to communicate with the cloud server. Let us discuss this code in detail.

Cloud Arduino code: elins_edu_axis_code1.zip, Download it from link below:

Unzip the file and open the .INO file

We have completed following steps upto now:
# Elins Cloud Registration (Got IIOT Web Panel from it).
# Cloud Arduino Device Code (NodeMCU is ready and communicating with Elins Cloud)

Now Let us RUN the complete IOT Ecosystem all together. For this follow the steps below:

This is IIOT Web Panel to see Realtime vehicle running Status Cloud Data Update and Theft monitoring using accelerometer sensor :







Step4: Give Power supply to IOT Kit, Now device LED is blinking, it means device connected with internet.Now real-time data will be displayed on this IIOT Web Panel. To see How this IIOT Ecosystem Work all together, watch this video :
