• Capacitive Proximity Sensors can be used to detect levels of liquid in a container. I have these on the outside of my RV holding tanks to detect how full waste water tanks are. This info is sent to the LCD controller screen via CANBUS.

• Layout
  • Each node must be within 30cm of the bus cable.
  • 1mb/sec is good for up to 40 meters.
  • Not sll ESP32's support CANBUS but All ESP32-WROOM chips do. They have an integrated Can controller but DO NOT HAVE A TRANSCEIVER.
    
    As such, we do not need SPI and the MCP2515 board. We can use a TJA1050 Transceiver module and connect UTP wires between the MCU and TJA1050!!
