ESP32 Interfacing With LM35

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

When LM35 Sensor Detect The Low Temperature

When LM35 Sensor Detect The High Temperature

Code :- 

//Prateek //www.prateks.in //https://www.youtube.com/c/JustDoElectronics #define ADC_VREF_mV 3300.0 #define ADC_RESOLUTION 4096.0 #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); }

Result
