ESP8266 Magnetic Sensor Project

This project demonstrates how to use the ESP8266 microcontroller with a Hall effect sensor to detect the presence of a magnetic field. The Hall effect sensor outputs a digital signal based on whether a magnet is present near it.

Components Needed

Circuit Setup

1.Connecting the Hall Effect Sensor to ESP8266:

Connect the digital output pin of the Hall effect sensor module to GPIO pin D1 on the ESP8266.

Ensure proper power (VCC) and ground (GND) connections between the ESP8266 and the Hall effect sensor module.

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 whether a magnet is detected ("Magnet Detected") or not ("No Magnet Detected").

Ensure that a magnet is brought close to the Hall effect sensor to observe changes in detection status.

Applications

Proximity Detection: Detect the presence of magnets or magnetic materials in proximity.

Door/window Sensors: Use in security systems to detect opening/closing of doors or windows equipped with magnets.

Industrial Automation: Monitor the position of machinery parts using magnets.

Notes

Magnet Strength: Different magnets may affect the detection distance and reliability of the Hall effect sensor.

Serial Communication: Use Serial Monitor for real-time monitoring of magnet detection status.

Digital Output: The Hall effect sensor outputs a digital signal (HIGH or LOW) based on whether a magnetic field is detected.
