  • A couple of years ago I experimented with your pH sensor and found it good. I will try to make a short answer here. Stay tuned. – tlfong01 20 mins ago   
  • what is preventing you from hooking it up? … please ask a specific question … any help? is not an answerable question because it is not about anything – jsotola 9 mins ago

Question

How can Rpi read DIY PH-4502C pH Sensor?


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.
