Heat Sensor Circuit Using Thermistor Bc547 Transistor Vrogue Co Working explanation. lm35 is an application of a digital thermometer and it also measures the temperature. it is a very famous and inexpensive temperature sensor. its output varies according to the temperature around it. the range of the lm35 ic lies between 55 degrees to 150 degrees. if the temperature is 0 degrees the output will also be 0v. When the temperature increases, the output of the lm35 temperature sensor increases as a rate of 10mv 0c. if the temperature reaches a certain threshold, the non inverting input of the op amp becomes higher than that of the non inverting input and as a result, the output of the op amp lm358 becomes high. this in turn will turn on the relay.
On Off Temperature Controller Circuit Diagram The temperature sensor circuit diagram using lm35 is surprisingly simple. it requires four external components: an lm35 temperature sensor, a power source, two resistors, and an led. the lm35 is connected to the power source, usually a 9 volt battery, via two resistors. The ic1 741 is configured as a comparator circuit. its pin#3 which is its non inverting input pin, is attached with the output of the heat sensor ic2 lm35. the inverting input pin#2 of ic1 is configured with a preset p1, which is used for setting the reference voltage at pin#2. whenever pin#3 voltage exceeds pin#2 voltage, the ic1 output at pin. This circuit diagram is used to measure temperature using the popular and precise lm35 temperature sensor. it features a precision integrated circuit temperature sensor that provides a precise voltage output that is linearly proportional to the celsius (centigrade) temperature, making it a solid starting point for those new to the field. The temperature sensor switch is built across the two ics lm35 and lm358. the relay in the circuit activates any electronic circuit connected to it when lm35 senses the desired temperature level. furthermore, the circuit is very simple involving just the two ics, a transistor, and a relay connecting other electronic devices circuits.

Lm35 sensor features. minimum and maximum input voltage is 35v and 2v respectively. typically 5v. can measure temperature ranging from 55°c to 150°c. output voltage is directly proportional (linear) to temperature (i.e.) there will be a rise of 10mv (0.01v) for every 1°c rise in temperature. ±0.5°c accuracy. Converting the lm35 output voltage into temperature. to convert the output voltage of the sensor into the temperature in degree celsius, you can use the following formula: temperature (°c) = vout 10. with v out in millivolt (mv). so if the output of the sensor is 750 mv, the temperature is 75°c.
