Over-temperature monitoring warning(LM35、LM741) circuit diagram is shown as above. The over-temperature monitoring alarm circuit uses the integrated circuit temperature sensor as temperature measurement device. It only sets a maximum limiting temperature control points. When the temperature exceeds the limit temperature, the alert sounds, prompting the user to pay attention. The parts of the circuit is shown in the figure. It is composed of the temperature detector, over-temperature monitoring circuit, warning sound occurs and the output circuit.
