D203B Dual Elements Passive Infrared PIR Sensor Used for Alarm System

Description

D203B Dual Elements Passive Infrared (PIR) sensor is commonly used in security and alarm systems for detecting motion. Here’s a detailed overview of its features, specifications, and applications:

Key Features:

  1. Dual Element Design:

    • Equipped with two sensing elements that enhance sensitivity and reduce false alarms by detecting temperature changes across a wider area.
  2. Passive Infrared Technology:

    • Detects infrared radiation emitted by objects (like humans) in its field of view. Since it’s passive, it doesn’t emit any energy but rather measures the infrared radiation.
  3. Wide Detection Range:

    • Typically has a detection range of up to 12 meters (about 39 feet) depending on the installation height and environment.
  4. Adjustable Sensitivity:

    • Many models allow you to adjust the sensitivity and detection range, making it versatile for various applications.
  5. Low Power Consumption:

    • Designed to operate on low power, making it suitable for battery-operated systems.
  6. Output Type:

    • Often provides a digital output (on/off signal) that can easily interface with microcontrollers, alarm systems, or automation devices.
