LM35 Temperature Sensor - Gravity

The DFRobot LM35 Linear Temperature Sensor is based on the semiconductor LM35 temperature sensor. It can be used to detect ambient temperature. This sensor is produced by National Semiconductor Corporation and offers a functional range between 0 to 150°C with a sensitivity of 10mV/°C. The output voltage is proportional to the temperature.

DFR0023-003

It includes thermocouples, platinum resistance, thermal resistance and temperature semiconductor chips, which are commonly used in high temperature measurement thermocouples. Platinum resistance temperature modules are used in measurements of 800 degrees Celsius, while the thermal resistance and semiconductor temperature sensor suitable for measuring the temperature of 100-200 degrees or below. In this type of application, the semiconductor temperature sensor has good linearity and high sensitivity.

Sample Code



void setup()
{
    Serial.begin(9600);//Set Baud Rate to 9600 bps
}

void loop()
{
    uint16_t val;
    double dat;
    val=analogRead(A0);//Connect LM35 on Analog 0
    dat = (double) val * (5/10.24);
    Serial.print("Tep:"); //Display the temperature on Serial monitor
    Serial.print(dat);
    Serial.println("C");
    delay(500);
}
