Sensors - one to many?

[olewsaa]

I have been working along the same lines, you might get some ideas from my projects. See my project pages. I have tried to avoid the cables, only exception is the gyro, magnetometer etc which run over some distanse using an I2C extender. The rest of the data if sent as SignalK messages using wifi, ESP8266 or ESP32.  The Arduino is a small less powerful microcontroller, while specially the ESP32 is quite a powerful dual core SoC. In addition one can use the Arduino IDE and recycle the programming skills used to program the Arduino. In addition you can use other languages and IDEs to program the ESPs.

Have fun,
