Dfrobot with mcp3008

[Acsreef]

Hi I'm new to the site I've been reedi g up on some post of reefpi and got the controller to work with relative ease, its currently monitoring temp, and Controlling 8 equipment relays, need help with Dfrobot anolg Ph probe and mcp3008 integration on the reefpi 3.0
Any diagram and coding suggestion wiil help. Thnx in advance

Hi! Welcome to Reef2Reef.

I'm glad to hear that you were able to get reef-pi running temperature and relays pretty easily. I've been very happy with my builds.

We recently introduced new driver based functionality in reef-pi v3. We don't have a driver for mcp3008 yet, but it could be added if you are comfortable with programming. We don't have anything using SPI so far; I would recommend finding an ADC that supports I2C instead. SPI is possible, but we don't have any example code with that protocol.

You may also need to add isolation for a reliable pH reading.

Thanks for the reply I'll have a look around to see where I can find a i2c interface. Will keep you posted. In meanwhile I'll try some coding options,
