The circuits were designed to illustrate the functions of two switches with the use of a single op-amp to show the operations of a precision light sensitive switch and a differential switch. LM741 – a ...

Starting with the sensor, measuring and controlling temperature is an essential building block of process industries. Automatic control in continuous processes uses industrial control systems to ...

It sounds rather mysterious: a switch that is controlled by its ambient temperature. All without the touch of a human hand, except for when you’re building this sort of electronic thermostat. There ...
