Hello everyone!
Today, I am thrilled to introduce you to a new and exciting project that I have crafted out of my passion and curiosity. This project is a “Smart Surveillance System” designed to enhance security in homes or offices. It incorporates powerful and versatile components such as the ESP32 CAM, ESP8266, relay module, ultrasonic sensor, buzzer, and buck converter.
The core idea behind this project is to immediately detect when an unfamiliar person or object enters our surveillance area and collect visual data about them. For this purpose, I have designed a system that utilizes an ultrasonic sensor to detect nearby objects. When an object is detected, the buzzer goes high and the relay is turned on. With the relay activated, the ESP32 CAM is powered on to begin capturing pictures automatically. The captured images are then sent to Google Drive using the ESP8266.
This project is not only useful for security purposes but also holds potential for smart homes or offices. I am excited to share this project with all of you through a detailed blog so that you can integrate this innovative surveillance system into your own projects and make your surroundings even more secure.
Components Used
- ESP32 CAM: This serves as the main controller and camera module, responsible for capturing images when triggered by the system.
- ESP8266: Used for Wi-Fi connectivity to upload captured images to Google Drive.
- Relay Module: Controls the power supply to the ESP32 CAM, turning it on when an object is detected by the ultrasonic sensor.
- Ultrasonic Sensor: Detects nearby objects and triggers the system to activate the relay and capture images.
- Buzzer: Provides audible feedback when an object is detected by the ultrasonic sensor.
- Buck Converter: Regulates the voltage to ensure stable power supply to the components.
Functionality
- Ultrasonic Sensor Detection: The ultrasonic sensor continuously monitors the surveillance area. When it detects an object within a certain range, it triggers the system.
- Buzzer Activation: Upon detecting an object, the buzzer emits a high-pitched sound to alert nearby individuals.
- Relay Control: The relay is activated when the ultrasonic sensor detects an object, allowing power to flow to the ESP32 CAM.
- Image Capture: With power supplied, the ESP32 CAM starts capturing images automatically.
- Google Drive Integration: The ESP8266 facilitates the upload of captured images to Google Drive for storage and remote access.
Testing and Results
During testing, the system consistently detected objects within the specified range of the ultrasonic sensor. The relay and buzzer were activated promptly upon detection, and the ESP32 CAM successfully captured images. Images were uploaded to Google Drive seamlessly via the ESP8266 module.
Conclusion
In conclusion, the Smart Surveillance System effectively combines various components to provide enhanced security and surveillance capabilities. Its ability to detect and capture images of objects in real-time, coupled with remote access via Google Drive, makes it a valuable asset for home and office security applications.
