Description

The D203S Human Infrared Module employs a passive infrared (PIR) sensor element paired with a Fresnel lens and signal conditioning circuitry. It detects changes in infrared radiation emitted by moving warm bodies, such as humans, within its field of view. The onboard comparator converts the analog signal into a clean digital output, simplifying integration with control systems.

Engineered for reliability in indoor environments, the module is designed for straightforward implementation in DIY electronics, home automation projects, and basic security setups. Its low-power operation makes it suitable for integration into energy-conscious designs.

Key Features

  • Passive Infrared (PIR) sensing principle for reliable human motion detection.
  • Integrated Fresnel lens to focus IR radiation and define the detection pattern.
  • Onboard signal processing for stable digital output and reduced false triggers.
  • Compact PCB module with standard 2.54mm pin headers for easy prototyping.
  • Wide operating voltage range compatible with common 3.3V and 5V logic systems.
  • Optimized performance-to-cost ratio for high-volume automation and security applications.

Applications

  • Security system intrusion detection and alarm triggering.
  • Automatic lighting control in corridors, stairwells, and rooms.
  • Occupancy sensing for smart home automation and energy management.
  • Presence detection for interactive displays or vending machines.
  • DIY robotics and projects requiring basic motion-activated triggers.

Frequently Asked Questions

What is the operating voltage range for the D203S module?

The D203S module typically operates within a 3.3V to 5V DC range. Always verify the specific voltage requirements on the module's PCB or datasheet before connecting power to ensure proper function and avoid damage.

How do I interface the D203S with an Arduino or Raspberry Pi?

Connect the module's VCC and GND pins to your board's 5V/3.3V and GND, respectively. The digital output pin connects to any digital input pin on the microcontroller. The output will go HIGH when motion is detected and LOW when idle, which can be read using a simple digitalRead() function.

What is the detection pattern and field of view for this sensor?

The D203S uses a Fresnel lens to create a wide, fan-shaped detection zone. The exact field of view (often around 110-120 degrees) and detection pattern (multiple zones) depend on the specific lens used. It is designed to detect lateral movement across the sensor's field, not direct approach.
