Description

The Senba D203S Passive Infrared (PIR) sensor utilizes a dual-element pyroelectric detector to sense changes in infrared radiation caused by moving objects, such as humans. Its analog output provides a raw voltage signal proportional to the intensity of the detected motion, offering greater flexibility for signal processing and threshold adjustment compared to digital sensors.

Housed in a robust TO-5 metal can package, the sensor features a high transmittance window and is designed for long-term stability across a wide temperature range. When paired with a standard Fresnel lens, its effective detection range can exceed 8 meters, making it suitable for perimeter security and automated lighting systems.

Key Features

  • Analog Output Flexibility: Delivers a high-amplitude, raw voltage signal (≥3500mV Vp-p) for custom signal conditioning and processing algorithms.
  • Wide Voltage Compatibility: Supports a broad 3-15V DC input range, enabling direct use with 3.3V, 5V, and 12V logic systems without additional regulation.
  • Optimized Spectral Sensitivity: Dual-element IR receiving electrode tuned to the 5–14μm wavelength band, precisely matching human body heat emission.
  • Industrial-Grade Temperature Range: Maintains specified performance across extreme conditions from -30°C to +75°C.
  • Low-Noise Design: Engineered for a clean output with less than 70mV of peak-to-peak noise, enhancing detection accuracy in electrically noisy environments.
  • Stable Offset Management: Features a controlled offset voltage range (0.3–1.2V) for reliable baseline signal establishment.

Applications

  • Outdoor security lighting and porch light automation with motion activation.
  • Energy management systems for occupancy detection in commercial buildings.
  • Perimeter intrusion detection for DIY and professional security systems.

Frequently Asked Questions

What is the output signal type of the D203S sensor?

The D203S provides an analog voltage output signal. It generates a raw, high-amplitude AC waveform (≥3500mV peak-to-peak) superimposed on a DC offset voltage (0.3–1.2V). This analog output requires external signal conditioning, such as amplification and comparator circuits, to convert the motion event into a digital trigger for microcontrollers like Arduino or PLCs.

What is the required supply voltage and current consumption?

The sensor operates on a wide DC voltage range from 3V to 15V, making it compatible with 3.3V, 5V, and 12V systems. While the exact quiescent current is not specified, PIR sensors of this type typically have very low power consumption, often in the microamp range, which is ideal for battery-powered or energy-harvesting applications.

Does this sensor module include a Fresnel lens?

No, this listing is for the sensor module only. The D203S PIR sensor must be paired with an external Fresnel lens to focus infrared radiation onto its dual-element detector and define the detection field of view (FOV). Standard Fresnel lenses can extend its effective detection range beyond 8 meters and shape the coverage pattern for specific applications like hallway sensing or wide-area coverage.

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

Direct connection to a microcontroller's digital input pin is not possible due to the analog output. You must first condition the signal. Typically, the output is connected to a high-gain operational amplifier circuit to boost the signal, followed by a comparator to create a clean digital pulse. This digital signal can then be read by an Arduino or Raspberry Pi GPIO pin. Alternatively, the raw analog output can be sampled using an ADC (Analog-to-Digital Converter) pin for more advanced motion analysis.
