Description

The Senba SB612A Smart Motion Module utilizes a passive infrared (PIR) sensing element paired with a Fresnel lens to detect the thermal radiation emitted by moving human bodies. The module’s signal conditioning circuitry filters out ambient thermal noise, triggering a reliable output signal upon valid motion detection. Its design prioritizes low-power operation, making it suitable for battery-powered IoT devices and wireless sensor nodes.

Engineered for environmental resilience, the module operates reliably across an industrial temperature range from -25°C to +55°C. The onboard potentiometers allow for precise field calibration of the detection delay and the ambient light threshold (lux), enabling customization for specific application environments like daylight-only activation or prolonged output hold times.

Key Features

  • Pyroelectric Infrared Sensing: High-sensitivity PIR element for reliable human motion detection.
  • Adjustable Field Parameters: Onboard trimmers for customizing delay time (2.3s to 80min) and ambient light activation threshold.
  • Dual Output Modes: Offers a 3.0V logic-level signal for microcontrollers and an open-collector output for directly driving relays or LEDs (100mA max).
  • Ultra-Low Power Design: Quiescent current below 50µA enables extended operation in battery-based systems.
  • Wide-Angle Fresnel Lens: Standard 24mm lens provides a broad 120° detection field of view.
  • Broad Voltage Compatibility: Supports 3.0V to 12V DC input, accommodating 3.3V and 5V logic systems seamlessly.
  • Compact & Ready-to-Use: Fully assembled module with all necessary passive components on a 24x32mm PCB.

Applications

  • Battery-powered security lights and outdoor lighting automation.
  • IoT-based occupancy sensing for smart home and office energy management.
  • Intruder alarm systems and wireless motion-triggered notifications.
  • Automatic door activation and presence detection in restrooms or storage areas.
  • Low-power wake-up triggers for microcontroller-based monitoring devices.

Frequently Asked Questions

What is the operating voltage range for the SB612A module?

The SB612A module operates from a wide DC voltage range of 3.0V to 12V. This makes it directly compatible with common 3.3V and 5V microcontroller systems like Arduino, ESP32, and Raspberry Pi without requiring a level shifter.

How do I adjust the delay time and light sensitivity (lux)?

The module includes onboard potentiometers for adjustment. Turn the 'DELAY_TIME' pot to set the output hold duration from 2.3 seconds up to 80 minutes. Adjust the 'DARK_ADJ' pot to set the ambient light level threshold at which the sensor becomes active.

What types of output does this motion sensor provide?

It provides two output options: a 3.0V high/low logic-level signal on the TEST pin for direct microcontroller input, and an open-collector output between LOAD+ and LOAD- pins capable of switching loads (like relays or LEDs) up to 100mA. The output voltage matches your supply voltage (Vcc).

What is the maximum detection range and field of view?

The integrated 24mm Fresnel lens provides a detection angle of up to 120 degrees, with a maximum sensing range of approximately 8 meters for standard human motion under typical environmental conditions.

Is this sensor suitable for battery-powered projects?

Yes, its ultra-low quiescent current (≤50µA, with the PIR sensor itself drawing ≤20µA) makes the SB612A ideal for battery-powered IoT devices, wireless sensors, and solar-powered lighting controls where energy efficiency is critical.
