12V PIR Motion Sensor Switch Module

This DIY PCB is designed for hobbyists and DIY enthusiasts who want to create their own motion sensor-based projects. The PCB is pre-designed with the PIR motion sensor HC-SR501, a BD139 transistor, a relay, a DC jack for input power, and an output connector for dry contacts.

Applications:

  • Home security systems: The PIR motion sensor can detect motion within a specified range, triggering the relay to activate a security system or alert the user.
  • Automated lighting: The motion sensor can be used to automatically turn on lights when someone enters a room and turn them off when they leave.
  • Energy-saving: The motion sensor can also be used to switch off appliances automatically when they are not in use, reducing energy consumption and costs.
  • Industrial automation: The PCB can also be used in industrial automation for various applications, including detecting movement of goods on conveyor belts or machinery.

Benefits:

  • Easy to use: The pre-designed PCB makes it easy to build a motion sensor project without the need for advanced technical skills.
  • Cost-effective: Buying the PCB and components separately can be cheaper than buying a pre-assembled motion sensor system.
  • Customizable: The DIY PCB allows for customization and experimentation with different components and configurations.
  • Compact design: The small size of the PCB makes it ideal for projects with limited space.

Features:

  • PIR motion sensor HC-SR501: The high sensitivity and low power consumption make this sensor ideal for motion detection.
  • BD139 transistor: The transistor amplifies the signal from the PIR motion sensor, allowing it to drive the relay.
  • Relay: The relay is used to activate or deactivate other components in the circuit, such as lights or security systems.
  • DC jack for input power: The DC jack allows for easy input of power to the circuit.
  • Output connector for dry contacts: The output connector provides a safe and convenient way to connect to other components in the circuit.

Specifications:

  • Power supply: DC 5V – 20V
  • Quiescent current: <50uA
  • Trigger current: 3mA ( sensor Current)
  • Detection distance: up to 7 meters
  • Detection angle: 110 degrees

In summary, this DIY PCB for PIR motion sensor HC-SR501 with BD139 transistor and relay is a versatile and cost-effective solution for motion detection and automation projects. With its customizable design, easy-to-use features, and compact size, it is ideal for hobbyists and DIY enthusiasts looking to create their own motion sensor projects.
