PIR Motion sensor
A PIR (Passive Infrared) Motion Sensor is a highly effective and reliable device used in various security and automation systems to detect motion. It operates by sensing infrared radiation emitted from objects, such as human bodies, within its detection range. When a person or animal enters the sensor's field of view, the sensor picks up the change in infrared radiation, triggering an alert or action, such as activating an alarm or turning on lights.
These motion sensors are commonly employed in home security systems, commercial alarm setups, and automated lighting systems, providing an efficient way to monitor activity within an area. They are typically mounted on walls or ceilings at a height of around 2.1 to 2.5 meters for optimal performance.
PIR sensors are designed for low power consumption, making them ideal for long-term use in battery-powered or wired systems. They typically operate on 12V DC or 24V DC power, depending on the model. Many PIR motion sensors also feature pet immunity options to prevent false alarms triggered by small animals, and sensitivity adjustments to fine-tune detection range, helping reduce unnecessary alerts.
With adjustable time delay settings, PIR motion sensors are perfect for reducing false triggers from short, transient movements. Some models come with advanced features such as temperature compensation, digital signal processing, and tamper detection, ensuring reliability and preventing false alarms. Additionally, IP-rated models are available for outdoor use, providing weatherproof protection.
Overall, a PIR motion sensor is a cost-effective and versatile solution for enhancing security, controlling lighting, or automating systems in a wide range of environments. It provides users with a simple and efficient means of detecting movement, ensuring safety and convenience.
