Description

The SB612-02-0001-L module utilizes a high-quality pyroelectric infrared sensor paired with a Fresnel lens to detect changes in infrared radiation caused by human movement. Its integrated digital signal processor filters out environmental noise, ensuring stable and reliable trigger outputs. The module outputs a digital high/low signal compatible with microcontrollers and logic circuits.

Engineered for durability, the module operates reliably across an industrial temperature range from -20°C to +55°C. The metal housing not only provides mechanical protection but also acts as a Faraday cage to shield the sensitive analog front-end from external RF and electrical noise, which is critical for installations near motors, relays, or switching power supplies.

Key Features

  • Advanced PIR Sensing: Equipped with a high-gain, low-noise amplifier chain for precise motion detection.
  • Digital Signal Conditioning: On-board processor provides clean, debounced output signals, eliminating false triggers.
  • Multi-Parameter Adjustment: User-configurable potentiometers for sensitivity (SENS), delay time, and ambient light threshold (DARK_ADJ).
  • Repeatable Trigger Logic: Output remains active as long as motion is detected within the delay window, ideal for occupancy sensing.
  • Robust Environmental Specs: Operates from -20°C to +55°C with a wide 3.8V to 12V DC supply range.
  • Anti-Interference Design: Metal enclosure with dedicated grounding pin significantly reduces susceptibility to EMI/RFI.

Applications

  • Automatic lighting control and energy management systems in commercial buildings.
  • Security and intrusion detection systems for perimeter monitoring.
  • Occupancy sensing for smart HVAC (Heating, Ventilation, and Air Conditioning) control.
  • Automatic door openers and presence-activated displays in retail environments.
  • Battery-powered, wireless IoT nodes for motion-triggered data logging.

Frequently Asked Questions

What is the output signal type of the Senba SB612 module?

The module provides a clean digital output signal, switching between a logic high and logic low level when motion is detected. This TTL-compatible output can be directly connected to the digital input pin of a microcontroller like an Arduino or Raspberry Pi GPIO for easy integration.

How do I adjust the sensitivity and delay time?

The module features three onboard potentiometers for adjustment. The 'SENS' pot controls detection sensitivity. The 'TIME' pot sets the output hold duration from 2 seconds to 70 minutes after the last detected motion. The 'DARK_ADJ' pot sets the ambient light level below which the sensor will activate.

What is the purpose of the metal casing and grounding pin?

The metal casing acts as an electromagnetic shield, protecting the sensitive analog sensor circuitry from external noise sources like motors or switching power supplies. The dedicated grounding pin should be connected to the system ground plane to maximize this anti-interference performance, ensuring reliable operation in electrically noisy environments.

Can this sensor be used outdoors?

While the module operates from -20°C to +55°C, the standard unit is not weather-sealed (IP-rated). For outdoor use, it must be installed inside a protective, weatherproof enclosure that has a clear window for the Fresnel lens. Direct exposure to rain, moisture, or condensation is not recommended.
