LM35 Temparature Sensor With Arduino : Its quite an easy project...Lets Start It... Just connect the LM35 sensor to the arduino and run the code below... CODE : //TMP36 Pin Variables int sensorPin = 0; //the analog pin the TMP36's Vout (sense) pin is connected to //the resolution is 10 mV / degree centigrade with a //500 mV offset to allow for negative temperatures /* * setup() - this function runs once when you turn your Arduino on * We initialize the serial connection with the computer */ void setup() { Serial.begin(9600); } void loop() { int reading = analogRead(sensorPin); // converting that reading to voltage, for 3.3v arduino use 3.3 float voltage = reading * 5.0; voltage /= 1024.0; // print out the voltage Serial.print(voltage); Serial.println(" volts"); // now print out the temperature float temperatureC = (voltage - 0.5) * 100 ; Serial.print(temperatureC); Serial.println(" degrees C"); // now conve...
