Guys, In this project we are going to monitor the temperature on an LCD screen using temperature sensor. Okey,let's make it.
Components Required
| 1. | Arduino UNO | * 1 |
| 2. | Temparature Sensor(TMP36) | * 1 |
| 3. | LCD(16*2) | * 1 |
| 4. | Resister(220 Ohm) | * 1 |
| 5. | Jumper Wires | * 1 |
Circuit Diagram
Program
const int tmp = A0;
const int p = 8;
void setup()
{
lcd.begin(16, 2);
Serial.begin(9600);
pinMode(p, OUTPUT);
}
void loop()
{
digitalWrite(p,LOW);
int Temp = analogRead(tmp);
float volts = (Temp / 965.0) * 5;
float c = (volts - .5) * 100;
float f = (c * 9 / 5 + 32);
Serial.println(f);
lcd.setCursor(5, 0);
lcd.print(f);
delay(3000);
}
