The project presents a modular alarm system using ESP32, LoRa communication, and a camera module to detect events and send real-time alerts. It focuses on achieving low power consumption, long-range connectivity, and cost efficiency.
In many smart home systems, the design is often monolithic and non-modular, making it difficult and expensive to integrate new functionalities.
This project focuses on developing a modular alarm unit that can be easily incorporated into a larger smart home network.
The system is based on an ESP32 microcontroller, HPD13A LoRa transceiver, and ESP32-CAM module, allowing for wireless communication and image capture when an event is detected.
A custom PCB was designed and implemented after careful analysis and selection of suitable low-power, compact, and cost-efficient components.
The device operates on a rechargeable battery and can also be powered using an external DC-DC converter. It transmits a signal only when an event, such as smoke detection, occurs, ensuring minimal power consumption and efficient operation. Overall, the project demonstrates the potential of a modular, scalable, and energy-efficient alarm system for smart home applications.
