Answer

1. DIY PH-4502C pH Sensor has an analog output. So you can use a multimeter to read the analog values and use a voltage to pH values table to find the pH value. You can also use Rpi to interface an ADC eg, MCP3008, and convert the ADC results to pH values.

2. I am summarizing some of my findings below.
