🔹 Step 2: Hardware Setup
Components:
-
Arduino board
-
LM35 sensor
-
Breadboard
-
Jumper wires
🔹 Step 3: Wiring Diagram
VCC → 5V
GND → GND
OUT → A0
🔹 Step 4: Code Implementation
float voltage;
float temperature;
void setup() {
Serial.begin(9600);
}
void loop() {
int reading = analogRead(sensorPin);
voltage = reading * (5.0 / 1023.0);
temperature = voltage * 100;
Serial.println(temperature);
delay(1000);
}
🔹 Step 5: Engineering Discussion
-
ADC resolution: 10-bit (0–1023)
-
Voltage reference: 5V
-
Conversion formula:
Temperature(°C)=Voltage×100Temperature (°C) = Voltage × 100
