Connect up to five Atlas Scientific sensors to one Arduino Uno / Mega. All Arduino pins still accessible through the i2 InterLink. Comes fully assembled. I2C mode only. i2 InterLink does not come with any EZO circuits or sensors. The Atlas Scientific i2 InterLink is designed for quick and straightforward integration with an Arduino, enabling the reading of various EZO devices. It is equipped with two isolated EZO circuit slots and one non-isolated slot, along with two additional non-isolated connectors specifically for 5-pin EZO data cable sensors or devices. This device features built-in electrical isolation, ensuring that sensors do not affect each other’s readings and significantly reducing the impact of external electrical disturbances on measurement accuracy. As an Arduino Shield, the i2 InterLink can be easily connected to any compatible Arduino board, providing a seamless user experience.
