I am currently working on a project which uses an ESP8266, accelerometer sensor and Raspberry Pi 4. The ESP module has to send the accelerometer data to the Raspberry Pi and the data has to be stored in the Raspberry Pi memory card in Excel or .csv format. I want the system to be portable so that there is no setting up process required when I take the system somewhere else. Just by switching on the Raspberry Pi and sensor, it automatically connects and starts sending data to the Raspberry Pi...
Is there a way to achieve this?
I am a beginner to Raspberry Pi and IoT, but I have basic knowledge in Arduino.
On the next level, I want multiple ESP modules to connect to a single Raspberry Pi (8). Is it possible?
