I’m relatively new to this and could use some advice on a build which would have the Bar30 sensor within a waterproof enclosure, transmitting its depth and temperature data 100m through a cable to a display on surface. Could you possibly point me in the right direction as to what kind of hardware I will need in addition to the sensor.
I was thinking:
Bar30 - 3.3to5v - Arduino Nano - i2c converter? - cat5 - converter to i2c? - Arduino Uno - lcd
Any help would be much appreciated.
