Motion Sensor Module Specifications and Features

Understanding the technical specifications and functional features of motion sensor modules is essential for engineers, integrators, and buyers alike. These components play a critical role in automation, security, energy efficiency, and environmental monitoring systems. Selecting the right motion sensor involves evaluating performance parameters such as detection capability, power efficiency, responsiveness, and durability. Below is a comprehensive breakdown of the key specifications and features that define modern motion sensor modules.

Detection Range and Angle

Detection Range

The detection range refers to the maximum distance at which a motion sensor can reliably detect movement. This typically varies from 3 to 15 meters for indoor PIR (Passive Infrared) sensors, while outdoor or industrial-grade units may extend up to 30 meters or more. The range is influenced by the sensor technology—PIR, microwave, ultrasonic, or dual-tech—as well as lens design and signal processing algorithms.

For example, in home security systems, a range of 10–12 meters is often sufficient to cover standard room sizes. In contrast, warehouse or perimeter monitoring may require long-range sensors with enhanced sensitivity and interference filtering.

Detection Angle

The detection angle defines the horizontal and vertical field of view (FOV) the sensor can monitor. Most PIR sensors offer a horizontal coverage of 90° to 120°, with some panoramic models reaching up to 180° or 360° using multi-lens arrays. Vertical angles typically range from 30° to 90°, depending on mounting height and orientation.

A wide detection angle is ideal for open spaces like lobbies or parking lots, where broad coverage is needed. Conversely, narrow-angle sensors are preferred for focused monitoring, such as hallways or entry points, to reduce false triggers from adjacent zones.

Power Consumption

Energy efficiency is a crucial factor, especially for battery-powered or wireless IoT devices. Motion sensor modules are generally designed for low power consumption to extend operational life and reduce maintenance costs. Passive Infrared (PIR) sensors are among the most energy-efficient, drawing only 10–100 µA in standby mode and peaking at 1–2 mA during activation.

In comparison, active sensors like microwave or ultrasonic types consume significantly more power due to continuous signal emission, often requiring 5–20 mA. This makes PIR sensors ideal for applications such as smart lighting, wearable trackers, and remote environmental monitoring systems where battery longevity is paramount.

Sensor Type	Standby Current	Active Current	Best Use Cases
PIR (Passive Infrared)	10–100 µA	1–2 mA	Smart homes, lighting control, battery devices
Microwave	5–10 mA	15–20 mA	Industrial automation, high-accuracy detection
Ultrasonic	5–8 mA	10–15 mA	Proximity sensing, robotics
Dual-Tech (PIR + Microwave)	8–15 mA	20–25 mA	High-security areas, reduced false alarms

Sensitivity Levels

Adjustable sensitivity allows users to fine-tune the sensor’s responsiveness to motion based on environmental conditions and application needs. High sensitivity enables the detection of small movements, such as a person breathing or slight hand gestures, making it ideal for medical monitoring, museum artifact protection, or occupancy detection in low-activity zones.

Conversely, lower sensitivity settings help prevent false alarms in high-traffic environments like office corridors, retail stores, or outdoor areas with moving foliage. Many advanced modules include digital sensitivity controls via software interfaces or potentiometers, allowing for precise calibration and zone-specific optimization.

Response Time

Response time—the delay between motion detection and signal output—is a critical performance metric in real-time systems. Fast response times (under 100 milliseconds) are essential in security alarms, automated doors, and robotic navigation, where immediate reaction is necessary to ensure safety or functionality.

Some budget or low-power modules may exhibit delays of 0.5 to 2 seconds due to signal filtering or energy-saving modes. While acceptable for lighting control or HVAC activation, such delays are unsuitable for time-critical applications. Dual-technology sensors often balance speed and accuracy by cross-verifying signals to minimize false positives without sacrificing responsiveness.

Environmental Resistance

For reliable operation in harsh conditions, many motion sensor modules are built with robust environmental protection. Key features include:

• IP Ratings: Modules rated IP65 or higher offer dust-tight and water-resistant enclosures, making them suitable for outdoor use in rain, snow, or high-humidity environments.
