Description

The Senba K222S PIR sensor utilizes a dual-element pyroelectric detector housed in a TO-5 package with a spectral response optimized for human body infrared radiation (8-14µm). Its core circuitry incorporates specialized filtering to reject interference from electromagnetic sources and visible light, critical for minimizing false triggers in challenging outdoor installations near lighting or electrical equipment.

Engineered for durability, the sensor operates across an extended temperature range from -20°C to +70°C. The analog output provides a variable voltage signal proportional to detected IR activity, allowing for seamless connection to the analog input channels of security cameras and monitoring systems without requiring complex digital protocol conversion.

Key Features

Interference-Immune Design: Integrated Anti-EMI and Anti-White Light circuits reject false triggers from RF noise and ambient light sources.
High-Performance Pyroelectric Core: Features a 2.6x1mm dual-element sensor with ≥3300V/W sensitivity and ≥75% IR transmittance for precise motion capture.
Outdoor-Proof Construction: IP65-rated enclosure ensures reliable performance against dust and water jets in harsh weather conditions.
Flexible Power & Integration: Wide 3-15V DC input range accommodates various power supplies; analog output simplifies system interfacing.
Extended Operational Range: Functions reliably across a broad -20°C to +70°C temperature span for all-season outdoor use.
Optimized Optical Assembly:
Precision 3x4mm Fresnel lens window focuses IR energy onto the sensor element to define the 110° detection pattern.

Applications

Outdoor perimeter security and intrusion detection systems for residential and commercial properties.
Motion-activated triggering for outdoor infrared CCTV cameras and wildlife monitoring cameras.
Gate and driveway automation systems requiring reliable presence detection in variable lighting conditions.
Industrial yard and asset protection systems where EMI from machinery is present.
Supplementary motion sensing for smart lighting and energy management systems in outdoor areas.

Frequently Asked Questions

What is the purpose of the Anti-EMI and Anti-White Light features on this sensor?

These features are designed to eliminate false triggers. The Anti-EMI circuitry suppresses interference from nearby motors, power lines, or radio frequencies. The Anti-White Light filter prevents sunlight, car headlights, or other bright ambient light sources from saturating the sensor, ensuring it only responds to genuine infrared heat signatures from moving objects.

How do I connect and power the Senba K222S PIR sensor?

The sensor requires a DC power supply between 3V and 15V connected to its designated V+ and GND terminals. The analog output pin provides a variable voltage signal that should be connected to the analog input of your camera, DVR, or controller. Always ensure polarity is correct and use the sensor within its specified voltage range for reliable operation.

Can this sensor be used indoors, and what is its IP65 rating for?

While it can function indoors, its core design is optimized for outdoor environments. The IP65 rating certifies it is dust-tight and protected against water jets from any direction, making it suitable for installation in exposed outdoor locations like eaves, walls, or gateposts where it may encounter rain and dust.

What is the detection pattern, and how should I mount it for optimal coverage?

The sensor has a 110-degree wide detection angle and a maximum range of approximately 12 meters. For optimal coverage, mount it at a height of 2-2.5 meters, angled slightly downward, and ensure the detection fan is clear of obstructions like bushes or fences. The fixed pattern is defined by the integrated Fresnel lens; it cannot be adjusted post-installation.
