ESP8266 Hall Magnetic Sensor Project

This project demonstrates how to use a Hall Effect sensor with an ESP8266 microcontroller to detect the presence of a magnetic field. It prints the status of the magnetic field (detected or not detected) to the Serial Monitor.

Components Needed

Circuit Diagram

Circuit Setup

1.Connecting the Hall Effect Sensor to ESP8266:

Sensor OUT Pin: Connect to a GPIO pin on ESP8266 (e.g., D1).

vcc: Connect to 3.3V or 5V pin on ESP8266.

gnd: Connect to GND pin on ESP8266.

Instructions

1.Setup:

Upload the provided Arduino code to the ESP8266 using the Arduino IDE.

Open the Serial Monitor to view the status of the magnetic field detection.

2.Testing:

After uploading the code, bring a magnet close to the Hall Effect sensor.

Observe the Serial Monitor output to see if the magnetic field is detected.

Applications

Proximity Sensing: Use in applications where proximity to magnets or magnetic fields needs to be detected.

Security Systems: Integrate into security systems for detecting door/window openings.

automation: Trigger actions based on the presence or absence of magnetic fields.

Notes

Sensor Orientation: Ensure proper alignment of the sensor and magnet for accurate detection.

Power Supply: Ensure the ESP8266 and the Hall Effect sensor operate within their specified voltage ranges.

interference: Minimize electromagnetic interference in the vicinity of the sensor for reliable operation.
