LM35 Temperature Sensor pins outLM35 is a Temperature sensor, its output voltage changes, based on the surrounding temperature. It is a small and inexpensive IC that can be used to measure temperature between -55 °C to 150 °C. It can easily connect with any Microcontroller that has AC/DC function or with Arduino. Lm35 IC by regulates voltage like +5V to the input pin and connected the ground pin to the ground of the circuit to measure the temperate in the form of voltage. LM35 Temperature Sensor pins outPin 1 receives a positive DC voltage typically 5 volts. The Pin 3 is the ground that receives the ground or negative current. The Pin 2 is the output of the IC that is used to get output from the temperature sensor. How Does LM35 Sensor WorkThe LM35 sensor is linear i.e. 10mv/°C which means that every degree rise in temperature by 10mv. In this way if the output of LM35 sensor is 220mv/0.22V the temperature will be 22 °C. If room temperature is 32 °C then the output of sensor will be 320mv i.e. 0.32V. Alternative to LM35 Temperature SensorIf you want to read the degree Fahrenheit then use LM34 Temperature sensor. It is same as LM35 but its electrical output is proportional to Degree Fahrenheit. LM34 has also same pins configuration and same voltage range same like lm35. LM35 Temperature Sensor Applications:
