Thirai Project - Smart Light
Smart Light ESP32 💡 Smart Light using ESP32 + PIR Project Details Controller ESP32 Sensor PIR Motion Sensor Output Relay + Light Level Beginner Overview
This project automatically turns ON a light when motion is detected using a PIR sensor and ESP32.
It helps in energy saving and smart automation systems.
Components ESP32 Development Board PIR Sensor Relay Module Bulb / Load Jumper Wires Connections PIR Sensor Connected to GPIO 14 Relay Module Connected to GPIO 26 ESP32 Code ESP32 Arduino Code Copy
#define PIR 14
#define RELAY 26
void setup(){
pinMode(PIR, INPUT);
pinMode(RELAY, OUTPUT);
}
void loop(){
int motion = digitalRead(PIR);
digitalWrite(RELAY, motion);
}
Output
When motion is detected, the light turns ON automatically.
When no motion is detected, the light turns OFF.
