I need to build a circuit to do the following: I am making some wine at home and need to monitor the process. During the fermentation process CO2 is produced so I need to monitor the pressure in the system and provide for a pressure release (back to 1.1 atm.) if the pressure gets too high (> 1.4 atm.). I also need to track the rate of pressure increase to determine if something is going wrong with the fermentation process. If the pressure is increasing > 0.01atm./hour for more than 5 hoursthe system needs to shut down by permanently opening the pressure release valve and turning on a red warning light. Finally, I need to determine when the wine is done (17% EtOH). I have a sensor to detect %EtOHwith an output of 1V/1% EtOH. When the EtOH concentration is at the correct level, a green light should be turned on and the pressure release valve permanently opened. Any ideas?
