SENSORS


Panasonic passive infra-red (PIR) sensors


The sensing ability in humans and animals shapes their lives and defines the way they interact with the surrounding world. We experience our environment and events taking place by way of specialized sense organs that send information to the brain. Without these sense organs our bodies become non-responsive, dependant and we lose the element of being a living being. Similarly, the electronics industry has long realized the important role of sensors in various products that help reshape our daily lives and the way we use products. Intelligent sensor technology can help save not only energy but also increase comfort and safety. The sensor industry has undergone major technology developments; significant growth and expansion over the past couple of decades, and the latest technologies allow us to integrate sensors in order to make these devices smart, effective and more energy efficient and thus offer additional benefits to the end users. Using passive infrared sensors is one of the most effective ways to achieve energy savings and offer freedom of design with ease of implementation. Built-in-sensors from Panasonic are used in a range of industries. Pressure Sensors are used in household appliances like washing machines and coffee machines. Acceleration Sensors are ideal for automotive and mobile devices. Light Sensors are used to regulate brightness for mobile devices, laptops and even TV. Motion Sensors are used in Lighting Management Systems (LMS), security and related applications. The longstanding PIR sensors from Panasonic are highly appreciated because of high sensitivity and accuracy. Panasonic offers a wide variety of PIR sensors with state-of-the-art technology, thanks to their comprehensive R&D and modern production facilities in Japan.


Key benefits of Panasonic PIR sensors include: » Compact design: Panasonic PIR sensor circuits are enclosed in a metallic case (TO5) which helps minimize the adverse effects of external


electro magnetic fields (i.e., radiated noise caused by cellular phones)


» Low current consumption: Specialized circuit reduces current consumption to 1µA during sleep mode. This maximises battery lifetime, which is optimal for battery-driven devices.


» Lead-free pyroelectric elements: Panasonic PIR sensors use lead-free lithium tantalite pyroelectric elements in comparison to the conventional PIR sensing elements made of ferroelectric ceramic (PZT).


» Panasonic PIR sensors are available in 2 categories defined by differences in lens shape:
