Make Fan Control Temperature Sensor Circuit Using Thermistor Yout Working of automatic temperature controlled fan using thermistor. it works on the principle of thermistor. in this circuit, pin 3 (non inverting terminal of op amp 741) is connected with the potentiometer and pin 2 (inverting terminal) is connected in between of r2 and rt1 (thermistor) which is making a voltage divider circuit. The temperature sensor circuit using a thermistor exploits the property of a sensor to operate the fan or any other device. this circuit also controls the temperature of any device according to the requirement of an industry. the main idea of a temperature sensor circuit is to control the speed of a fan by heating a thermistor. and the speed of.
How To Make Temperature Sensor Circuit Using Thermistor Youtube Working explanation. the basic working principle of the temperature control dc fan is based on the working of the thermistor. here, lm358 compares the voltage across the thermistor and the voltage across the resistor. at room temperature, the voltage across the thermistor will be greater than or equal to the voltage across the resistor. Step 2: connect all parts as the image above. this circuit uses a thermistor as a sensor, the thermistor resistance decrease when a temperature increase. when the temperature increases the thermistor resistance decrease until the voltage set point that adjusts by potentiometer higher than vgs threshold, mosfet change to on state and make a 12.
