provide instructions on what to purchase, how to construct and program a Raspberry Pi to monitor refrigerant superheat via a pressure transducer and thermistor. Then input a set point to open or close a pair of volt free contacts.

I am looking for help with a project to provide instructions on what to purchase, and how to construct and program a Raspberry Pi. To monitor refrigerant superheat (in particular refrigerant R404a). This would have to be done via a pressure transducer and thermistor. Then based on the reading, input a set point to open or close a pair of volt free contacts. I am a beginner with Raspberry Pi and so I am open to suggestions when it comes to components and parts for this project. The intended use of this Raspberry Pi monitor will be for personal use. I am looking for someone experienced with Raspberry Pi to help give me detailed instructions on where and what to buy, how to construct and program this device.
