This project is a template for an ESP32-based alarm system that uses PIR (Passive Infrared) sensors to detect motion. Here's a breakdown of the key components and their connections:
Components:
  • ESP32-DEVKIT-V1: Two ESP32 development boards (U1 and U2) are used in this project. These are the main microcontroller units that will process inputs from the PIR sensors and drive outputs like speakers.
  • PIR Sensors: Two PIR sensors, PIR1 and PIR2, are used to detect motion. Each is connected to a different ESP32 for motion detection.
  • Speaker (SPK1): This is a mini speaker connected to the circuit to produce alarm sounds upon motion detection.
  • Transistor (Q1): This is used to amplify the signal driving the speaker.
  • Resistor (R1): This is connected to the transistor base to limit the current.
Key Connections:
  • PIR1 Connections:
    • Connect PIR1:GND to U1:GND__1.
    • Connect PIR1:SOURCE to U1:D26.
    • Connect PIR1:DRAIN to Q1:C and U1:3V3.
  • PIR2 Connections:
    • Connect PIR2:GND to U2:GND__1.
    • Connect PIR2:SOURCE to U2:D26 and other U2 pins.
    • Connect PIR2:DRAIN to U2:3V3.
  • Speaker and Transistor Connections:
    • Connect Q1:E to SPK1:POSITIVE.
    • Connect SPK1:NEGATIVE to U1:GND.
    • Connect R1:P1 to U1:D25, and R1:P2 to Q1:B.
Project Functionality:
The ESP32 microcontrollers are responsible for monitoring the PIR sensors. When motion is detected by either sensor, the corresponding ESP32 could trigger an alarm sound through the speaker. The speaker is driven by a transistor to ensure sufficient current and amplify the signal.
This setup allows for a basic alarm system that can be expanded or modified according to specific needs, like adding wireless communication, additional sensors, or integrating it with other smart home systems.
