LM35 Temperature Sensor SEN21, R34

Fr2,000

This is a Temperature Sensor , The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature. The LM35 device is rated to operate over a 0°C to 100°C temperature range.

SKU: SEN672 Category:

Description

The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling.

  • Calibrated Directly in Celsius (Centigrade)
  • Linear + 10-mV/°C Scale Factor
  • 0.5°C Ensured Accuracy (at 25°C)
  • Rated for 0°C  to 100°C Range
  • Suitable for Remote Applications

Datasheet

Getting started with the LM35 Temperature Sensor

Now make your own temperature sensor by Arduino and LM35 Sensor

Hardware required

Connecting the Hardware

Connect the LM35 Temperature Sensor to the arduino UNO as shown below.

 

UPLOAD THE FOLLOWING CODE ON ARDUINO BOARD.

int val;
int tempPin = 1;

void setup()
{
Serial.begin(9600);
}
void loop()
{
val = analogRead(tempPin);
float mv = ( val/1024.0)*5000;
float cel = mv/10;
float farh = (cel*9)/5 + 32;

Serial.print(“TEMPRATURE = “);
Serial.print(cel);
Serial.print(“*C”);
Serial.println();
delay(1000);

/* uncomment this to get temperature in farenhite
Serial.print(“TEMPRATURE = “);
Serial.print(farh);
Serial.print(“*F”);
Serial.println();

*/
}

NOTE: IF you  get stray ‘223’ errors The problem is with your “ and ” characters. Replace them with ordinary quotes, ", and you should be fine.
