ESP32 Interfacing With LDR Sensor

In The Blog I will Just Interfacing LDR Sensor With Esp32 Board .The Output Will Display the Output of Serial Monitor .

Block Diagram :- 

Circuit Diagram :-

Here I Just The Interfacing The LDR Sensor 

In This Image Show The 10K Resister - 

Image Will Show The Code Of This Project

Serial Monitor Show The OutPut Of LDR

Code :-

//Prateek //www.prateks.in //https://www.youtube.com/c/JustDoElectronics #define LIGHT_SENSOR_PIN 33 // ESP32 pin GIOP33 (ADC0) void setup() { Serial.begin(9600); } void loop() { int analogValue = analogRead(LIGHT_SENSOR_PIN); Serial.print("Analog Value = "); Serial.print(analogValue); if (analogValue < 40) { Serial.println(" => Dark"); } else if (analogValue < 2000) { Serial.println(" => Dim"); } else if (analogValue < 2500) { Serial.println(" => Light"); } else if (analogValue < 4000) { Serial.println(" => Bright"); } else { Serial.println(" => Very bright"); } delay(500); }

Result
