Project description:
"IoT Smart Lock Device – Requirement Specification
1. Core Features

Location Tracking:

GPS/GNSS-based location tracking with real-time updates.

Motion & Vibration Monitoring:

3-axis accelerometer + gyroscope + vibration sensor for detecting movement, shocks, or tampering.

Live Audio Streaming:

Microphone with live audio/sound streaming capability over the IoT network.

Door Position Detection:

Sensor to detect current status/position of the door.

Preferably via a variable resistor/potentiometer or angle sensor to know the door’s exact position (open/closed/partial).

Touch Button Lock/Unlock Control:

Capacitive touch button to control DC motor for door locking/unlocking.

Limit switches integrated for safe motor stop at lock/unlock positions.

OLED Display:

Small display showing lock/unlock status and other info (status sync with Blynk IoT App).

Blynk IoT Integration:

Remote monitoring and control of lock/unlock.

Status updates: Locked, Unlocked, Tampered, Offline.

Data Logging (Offline Support):

SD card storage to log sensor data when offline.

Automatic data upload to cloud once the device is online.

Temperature Monitoring:

Self-adhering surface temperature sensor (160 mm probe) attached to the metal body.

Tamper Detection:

Hardware key/switch that detects if the box is opened without authorization.

2. Power & Backup

Minimum 24 hours backup on battery.

Fast charging support for quick recharge.

3. Connectivity

IoT-ready (WiFi + 4G/LTE preferred).

Device should push all data (location, lock status, vibration, temperature, tamper, logs) to the Blynk IoT app/cloud.

4. Data to be Monitored

GPS Location (Live tracking)

Vibration/Acceleration/Gyro Data

Live Audio Stream

Door Position (Locked/Unlocked/Partially Open)

Temperature (from surface sensor)

Tamper Detection (Box opened/closed)

Power/Battery Status

5. Hardware Requirements
