I am building a temperature control circuit to control water temperature. The temperature has to be regulated between 80-85°C. I'm using LM35 template sensor. And ua741 op amp.
My question is should I use two op amps to created a window comparator or use resistors to create schmitt trigger? What is the difference between the two?
