A fast and easy way to read multiple EZO devices from an Arduino. The Whitebox T2 has 2 isolated EZO slots, a non-isolated EZO slot and 2 connectors for the 5 pin EZO Data devices. Built in electrical isolation means that sensors won’t interfere with each other and most outside electrical noise that can interfere with readings is eliminated. Because it’s an Arduino Shield, it simply plugs into any compliant Arduino.
