PCB - Domestic Vibration Sensor

This is a compact PCB design for a home and industrial vibration detection system, capable of capturing precise motion and vibration data using a 6-axis IMU sensor and an ESP32-based microcontroller. Features:

1. 🌀 Motion & vibration detection using the MPU-6050 (3-axis accelerometer + 3-axis gyroscope)
2. 📶 Wi-Fi and Bluetooth connectivity via Arduino Nano ESP32
3. 🔋 Battery-powered operation from a 7.4 V Li-ion/LiPo pack with onboard 3.3 V regulation
4. 🔘 Hardware reset button with RC filter for stable system control
5. 💤 Low-power operation modes for extended battery life
6. 🏠 Ideal for smart home systems, appliance monitoring, and vibration analytics

Usage

To use the Domestic Vibration Sensor, follow these steps:

1. Connect a 7.4 V Li-ion/LiPo battery to the power input terminal.
2. Mount the PCB on the surface or object you wish to monitor (e.g., washing machine, air conditioner, motor).
3. Power on the system and connect via Wi-Fi or Bluetooth.
4. Access vibration data in real-time or log readings locally for later analysis.
5. Configure motion thresholds and alerts based on application needs.
6. The ESP32 automatically manages power and sensor interrupts for efficient operation.
7. The device can monitor subtle vibration patterns, detect abnormal activity, and send alerts or logs to a connected interface, making it perfect for home automation, predictive maintenance, and IoT condition monitoring.
