Temperature Sensor circuit using LM35 & IC741

Temperature Sensor using LM35 & Opamp

The Opamp IC 741 is used here as non-inverting non-zero reference comparator. Its inverting terminal is connected to variable voltage which can be adjusted with the help of variable resistor VR1. The non inverting terminal is connected to the output of temperature sensor LM35. The prototype works very effectively and responds to quick changes in…
