pH and Orp interface

Other Hardware Home Automation

Greetings,

I just published this project on Github.

This is a two-channel board for amplification, digitization (ADS1115, 16 bits) and galvanic isolation of pH and Orp probes, which can be used in projects such as swimming pools, spas, aquariums, etc.

Interfacing with Arduino is easily done via the I2C bus and the libraries that drive the ADS1115 ADC such as this one or that one.

Thanks Lou, may I ask where you had this manufactured?

JLCPCB or PCBWAY will manufacture the PCBs for you for a few bucks. Then I hand-soldered the components
