ESP8266 Light Sensors Project

This project focuses on using an ESP8266 microcontroller to read light intensity using a Light Dependent Resistor (LDR). The sensor value is then displayed on the Serial Monitor.

Components Needed

Circuit Setup

1.Connecting the LDR to ESP8266:

Connect one leg of the LDR to the 3.3V or 5V pin (depending on LDR type).

Connect the other leg of the LDR to analog pin A0 of the ESP8266.

Optionally, connect a resistor (e.g., 10kΩ) from the LDR's connection point to ground to create a voltage divider circuit for accurate analog readings.

Instructions

1.Setup:

Open the Arduino IDE with ESP8266 board support installed.

Create a new sketch and paste the provided Arduino code.

Connect the ESP8266 to your computer, select the appropriate board and port from the Tools menu.

Upload the code to the ESP8266.

2.operation:

After uploading the code, open the Serial Monitor(baud rate: 9600).

The Serial Monitor will display the light intensity value read from the LDR.

Observe changes in light intensity and corresponding sensor values.

Applications

Light Sensing: Monitor ambient light levels in indoor or outdoor environments.

automation: Trigger actions based on light levels, e.g., turning on lights when it gets dark.

Energy Efficiency: Optimize energy use based on natural light availability.

Notes

LDR Calibration: Adjust the code or circuit if needed based on specific LDR characteristics.

Serial Communication: Use Serial Monitor for real-time monitoring and debugging.

Analog Readings: Understand analog-to-digital conversion and sensor interfacing.
