25.ESP32 Interfacing With LM35

admin

In This Blog I will Just Interfacing LM35 Sensor With Esp32 Board They Will Show Analog Value In Serial Monitor.

Block Diagram :- 

Circuit Diagram :-

Image Will Show The Code Of This Project

#define ADC_VREF_mV    3300.0 
#define ADC_RESOLUTION 1024.0
#define PIN_LM35       33 

void setup() {
  Serial.begin(9600);
}

void loop() {
  int adcVal = analogRead(PIN_LM35);
  float milliVolt = adcVal * (ADC_VREF_mV / ADC_RESOLUTION);
  float tempC = milliVolt / 10;
  float tempF = tempC * 9 / 5 + 32;

  Serial.print("Temperature: ");
  Serial.print(tempC);   
  Serial.print("°C");
  Serial.print("  ~  "); 
  Serial.print(tempF);   
  Serial.println("°F");

  delay(500);
}
