Description

The Senba W216B Analog PIR Motion Sensor utilizes a dual-element pyroelectric sensor housed in a TO-5 package to detect changes in infrared radiation emitted by moving human bodies within its 5-14μm spectral response range. Its analog output provides a continuous voltage signal, offering greater granularity than digital on/off sensors, which is essential for advanced alarm systems that require motion intensity analysis.

Engineered for industrial and commercial security applications, the sensor features robust anti-EMI shielding to maintain accuracy in environments with significant electromagnetic interference. Its operational range from -20°C to 70°C ensures reliable performance in both indoor and sheltered outdoor installations, supporting integration into professional-grade intrusion detection and automated lighting systems.

Key Features

  • High-sensitivity dual-element pyroelectric sensor with ≥3300V/W responsivity for reliable human detection.
  • Broad 3-15V DC input voltage range compatible with 5V and 12V alarm system power rails.
  • TO-5 metal can encapsulation with ≥75% IR transmittance window for optimal signal integrity and durability.
  • Low-noise design with <70mV output noise ensures a clean analog signal for accurate processing.
  • Wide operating temperature range (-20°C to 70°C) suitable for challenging environmental conditions.
  • Compact form factor (6x4x1 cm) for discreet wall or ceiling mounting in security installations.

Applications

  • Commercial and residential anti-burglar alarm system intrusion detection.
  • Automated lighting control in warehouses, parking garages, and office buildings.
  • Energy management systems for occupancy-based HVAC and power control.
  • Industrial security monitoring in electrically noisy environments near machinery.
  • Battery-powered wireless sensor nodes for perimeter security.

Frequently Asked Questions

What is the output signal type of the Senba W216B sensor?

The Senba W216B provides an analog voltage output signal. The output voltage varies continuously in proportion to the intensity of the detected infrared radiation, allowing for precise motion level monitoring and adjustable trigger thresholds when connected to a microcontroller ADC or comparator circuit.

How does the anti-EMI feature benefit the sensor's operation?

The anti-EMI (Electromagnetic Interference) shielding minimizes false triggers and signal degradation caused by nearby electrical noise from motors, switching power supplies, or radio transmissions. This ensures reliable and accurate motion detection in industrial, commercial, or residential environments with high electromagnetic activity.

What is the power supply requirement for this PIR sensor?

The sensor operates from a wide 3V to 15V DC input range. This makes it compatible with common 5V microcontroller systems (Arduino, Raspberry Pi) and standard 12V security alarm panel power supplies, offering flexibility for both DIY electronics and professional security installations.

Can the detection sensitivity and range be adjusted?

Yes, the sensor's sensitivity can be adjusted, typically via an onboard potentiometer, to fine-tune its response. This allows you to tailor the detection range (up to 12 meters) and threshold to minimize false alarms from small pets, sunlight, or HVAC airflow while maintaining coverage of the intended area.
