From the project
This project is a Motion Detection and Alarm Mesh System built using four ESP32-WROOM-32 development boards communicating through ESP-NOW wireless communication.
This project is a Motion Detection and Alarm Mesh System built using four ESP32-WROOM-32 development boards communicating through ESP-NOW wireless communication.
The system is designed as a distributed wireless intruder alarm network where:
- One ESP32 acts as the Master Node - Three ESP32 boards act as Slave Nodes
The master node monitors motion using a PIR sensor and wirelessly broadcasts alarm triggers to all slave nodes. Each slave node independently activates its local alarm system whenever a trigger is received.
