PIR Infrared Sensor – wired
A PIR (Passive Infrared) sensor is an electronic sensor that detects infrared (IR) light radiating from objects within its field of view. It's called "passive" because it doesn't emit any energy itself; instead, it passively monitors the existing infrared radiation in its surroundings. All objects with a temperature above absolute zero emit some level of infrared radiation, and the hotter an object, the more radiation it emits. PIR sensors are particularly effective at detecting the infrared radiation emitted by warm bodies, such as humans and animals. How PIR Sensors Work At the core of a PIR sensor is a pyroelectric sensor, a material that generates an electrical charge when exposed to changes in infrared radiation. To detect motion, most PIR sensors use a dual-sensor design:- Dual Elements: The pyroelectric sensor is typically divided into two halves or elements, wired in a way that they cancel each other out when no motion is detected. This means that if both halves receive the same amount of IR radiation (e.g., from the ambient room temperature), their signals balance, and no output is generated.
- Fresnel Lens: A Fresnel lens is often placed in front of the pyroelectric sensor. This special lens has multiple facets that help to focus infrared light from different angles onto the sensor elements, increasing its range and sensitivity, and creating distinct detection zones.
- Motion Detection: When a warm object, like a person, moves across the sensor's field of view, it first enters one detection zone (and thus one half of the pyroelectric sensor) and then the other. This causes a differential change in the amount of infrared radiation impinging on each half of the sensor. This difference in IR energy between the two halves creates an electrical signal.
- Signal Processing: The sensor's internal circuitry processes this change in voltage. If the change is significant enough (indicating a "moving heat source"), the sensor triggers an output signal.
- Security Systems: The PIR infrared sensor are a fundamental component of burglar alarms and motion-activated security cameras, detecting intruders by their body heat.
- Automatic Lighting: PIR infrared sensors are used in homes, offices, and public spaces to automatically turn lights on when someone enters a room or area and off when it's unoccupied, leading to energy savings.
- Smart Home Automation: The PIR infrared sensor play a crucial role in smart homes, triggering various automated actions like adjusting thermostats, turning on appliances, or opening doors based on occupancy.
- Automatic Doors: Many automatic door systems, like those found in shopping malls, use PIR sensors to detect approaching individuals and open the doors.
- Industrial Monitoring: They can be used to monitor machinery movement or detect the presence of personnel in hazardous areas for safety purposes.
- Wildlife Tracking and Research: Researchers use them to monitor animal movements unobtrusively.

PIR Infrared Sensor – wireless
A wireless PIR (Passive Infrared) sensor is a type of motion detector that uses infrared technology to detect the presence and movement of people, animals, or other warm objects within its field of view, and then transmits this information wirelessly to a central control unit. Here's a breakdown of its key aspects: PIR (Passive Infrared) Technology:- Passive: The "passive" in PIR means the sensor does not emit any energy (like radar or ultrasonic sensors do). Instead, it "passively" detects the infrared radiation (heat energy) naturally emitted by all objects with a temperature above absolute zero.
- Infrared Detection: All living beings (humans, pets) and warm objects emit infrared radiation.
- How it works: A PIR sensor typically has two sensing elements within its housing. When no motion is present, both elements detect the same amount of infrared radiation from the ambient environment. When a warm body moves across the sensor's field of view, it first enters one sensing element's range, causing a rapid change in the infrared energy detected by that element. As the body moves further, it then affects the second element. This differential change in infrared energy between the two elements is what the sensor interprets as motion.
- Fresnel Lens: PIR sensors often have a specialized faceted lens (a Fresnel lens) on their front. This lens helps to focus the infrared radiation onto the sensing elements and creates multiple "detection zones" or "fingers" within the sensor's field of view, which increases its coverage and sensitivity.
- No Wires for Communication: The "wireless" aspect means the sensor communicates with the alarm system's control panel (or receiver) using radio frequencies (RF) rather than physical wires.
- Battery Powered: Wireless PIR sensors are usually battery-powered, making them easy to install anywhere without needing to run electrical wiring. The batteries typically last for a significant period (months to years) before needing replacement.
- Transmitter: Each sensor has a small radio transmitter that sends a signal to the central alarm panel when motion is detected.
- Receiver: The alarm control panel has a built-in or external wireless receiver that listens for signals from the PIR sensors (and other wireless sensors like door/window contacts).
- Easy Installation: No need for complex wiring, making DIY installation simpler and reducing labor costs for professional installers. This is a significant advantage in existing structures where running wires might be difficult or aesthetically unappealing.
- Flexible Placement: Can be mounted virtually anywhere within their effective range of the control panel, providing versatile coverage.
- Reduced False Alarms (Compared to Simple Motion Detectors): Because PIR sensors detect heat signatures, they are less likely to be triggered by non-living things like swaying curtains, blowing leaves, or shadows (though extreme drafts or sudden temperature changes can still be an issue if not properly installed).
- Pet Immunity: Many wireless PIR sensors offer "pet immunity" features. These sensors are designed to ignore the infrared signatures of smaller animals (below a certain weight, e.g., 40 lbs or 80 lbs), helping to prevent false alarms in homes with pets. This is achieved by adjusting the sensor's lens and internal logic to focus on specific infrared patterns that are indicative of human-sized targets.
- Energy Efficiency: As passive devices, they consume very little power, contributing to long battery life.
- Comprehensive Coverage: Ideal for protecting large areas or rooms, as a single sensor can cover a significant space.
- Integration: Seamlessly integrate with smart home security systems, allowing for remote monitoring, alerts via smartphone apps, and sometimes even integration with other smart devices (e.g., turning on lights when motion is detected).
- Home Security Systems: Widely used indoors to detect intruders in living rooms, hallways, bedrooms, and basements. Outdoor-rated versions are also available for perimeter protection.
- Commercial Security Systems: Protecting offices, warehouses, retail spaces, and other commercial properties.
- Automated Lighting: Activating lights in rooms, hallways, or outdoor areas when someone enters.
- Smart Home Automation: Triggering various smart home routines based on occupancy (e.g., adjusting thermostat, playing music).
- Access Control: Monitoring movement in restricted areas.
- Placement: Proper placement is crucial to avoid false alarms. Avoid aiming them directly at heat sources (vents, radiators, direct sunlight, fireplaces), areas with strong drafts, or windows (especially those exposed to direct sun or busy outdoor activity).
- Pet Immunity Settings: If you have pets, ensure the sensor has pet immunity and that it's set correctly for your pet's size and the sensor's mounting height.
- Signal Range: Ensure the sensor is within the wireless range of your alarm panel, considering walls and other obstructions that might weaken the signal.
- Battery Life: Be mindful of battery replacement schedules to ensure continuous operation.
