ESP32 Tilt Sensor Project

Project Overview

The ESP32 Tilt Sensor project demonstrates how to interface a tilt sensor with an ESP32 microcontroller to detect changes in orientation (tilt). The tilt sensor used in this project can be a simple tilt switch that changes state when tilted beyond a certain angle.

Components Needed

• ESP32 Microcontroller: Controls and processes sensor data.
• Tilt Sensor: Detects tilt or inclination changes.
• Jumper Wires: Connects the tilt sensor to the ESP32.
• Breadboard: Optional, for organizing circuit connections.

Circuit Setup

1. Connecting the Tilt Sensor to ESP32:
   • Digital Input: Connect the output pin of the tilt sensor to any GPIO pin on the ESP32 (e.g., GPIO 5).
   • Pull-up Resistor: Use pinMode(tiltSensorPin, INPUT_PULLUP) to enable the internal pull-up resistor on the GPIO pin connected to the tilt sensor.

Instructions

1. Setup:

   • Initialize Serial communication using Serial.begin(9600) for debugging purposes.
   • Configure the tilt sensor pin as input with internal pull-up resistor using pinMode(tiltSensorPin, INPUT_PULLUP).

2. Operation:

   • Reading Tilt State:
     • Use digitalRead(tiltSensorPin) to read the state of the tilt sensor (HIGH or LOW).
     • Print the tilt state to the Serial Monitor based on the sensor reading.

3. Output:

   • Display "Tilt detected!" if the tilt sensor detects a tilt (LOW state).
   • Display "No tilt detected." if the tilt sensor is not tilted (HIGH state).

4. Considerations:

   • Sensor Positioning: Ensure the tilt sensor is positioned correctly to detect the desired tilt angle.
   • Sensor Sensitivity: Adjust the sensor or circuit sensitivity if needed for specific tilt detection requirements.
   • Debouncing: Add debouncing techniques if the sensor output is unstable due to mechanical vibrations.

Applications

• Orientation Detection: Monitor tilt or inclination of objects or surfaces.
• Alarm Systems: Trigger alarms or notifications based on tilt events.
• Robotics: Detect orientation changes in robotic applications.
