in this video {1298} Adjustable Over Temperature Sensor or Over heat detector or adjustable electronic thermostat Using OPAMP LM324 or LM357 or LM741 or any comparator IC LM339. it is Awesome project How to make an adjustable over-temperature sensor using an LM324 op-amp is totally doable and great for learning how comparators work with temperature sensors. I used LM324 Operational amplifier OPAMP with open-loop gain acting as a comparator but it's not the same as a dedicated comparator as op-amp in open-loop mode means there is no feedback connecting the output back to the input. In this state the gain (A) is very high — often 100000 or more. Even a tiny difference between the non-inverting (+) and inverting (–) inputs will cause the output to saturate to either the positive rail (Vcc) or the negative rail (or GND). Thus that behavior is exactly what a comparator does.

What You’ll Build: An over-temperature detection circuit that turns on an LED or activates a fan/relay when the temperature exceeds a user-set threshold using:
LM324 (quad op-amp) with 12 volt dc power supply. 10K ohm NTC thermistor . 10K Potentiometer (for adjusting the threshold). LED with 1K ohm. 2x 10K ohm resistors. Breadboard/ connection wires.
