sensor-reading

For reading the sensors on the ROV and making nice, happy interfaces for them.

For PH probe: The PH probe is giving off a current that is generated from the hydrogen ion activity This number is the reciprocal of that activity and can be perdicted with this equation E = E^0 - (2.303RT/F)pH; R = ideal gas constant, T= temp in Kelvin, F = Faraday constant

says for connecting: either SMA cable to SMA breakout board or Female BNC and BNC to SMA adapter Just outputs a number Takes time to get an accurate reading

For temp sensor:

Something similair using I2C and Pi but diff temp sensor https://www.instructables.com/id/Reading-I2C-Inputs-in-Raspberry-Pi-using-C/ used Librarys: stdio, stdlib, string, stdint
