Panasonics Plug & Play PIR Motion Sensor Solution for Occupancy Detection & Presence Applications

The Panasonic NaPiOn and PaPIR are currently the world’s smallest PIR motion sensors with built in amplifier. Each micro sensor incorporates a high sensitivity Quad Pyro electric Element, an Integrated ASIC covering Analogue Signal Processing, Impedance Converter, Signal Amplifier and Window Comparators contained within a TO5 can, for high resistance to electromagnetic interference, fitted with a small multi-Lens for optimised performance. This is only achieved by using Patented MEMS technology, allowing a plug and play PIR solution for numerous presence detection and occupancy detection applications.

Furthermore, because all the components are enclosed in a single shielded housing in a TO-5 style case, Panasonic's motion sensors are significantly more tolerant to external interference from sources such as mobile phones. This greater shielding and high signal to noise ratio can help prevent false triggering and miss-operation of the control circuit.

Panasonic PIR sensors have been used in applications within the Smart Home, Building Automation, Lighting, HVAC, Security and Consumer Electronics markets for more than 20 years with millions of sensors being sold annually across the globe due to the proven performance and quality of the sensor.

Whatever the application within a market requiring occupancy or presence detection for energy saving or function activation, today everyone’s focus appears to be driven towards IoT or the actual connectivity of things.

The Internet of Things is the interconnection of uniquely identifiable embedded computing devices within the existing Internet infrastructure [Wikipedia]

The physical world itself is becoming a type of information system. Sensors and actuators are linked through wired and wireless networks, often using the same internet protocol (IP) that connects to the Internet. These networks churn out huge volumes of data that flow to computers for analysis [McKinsy & Company]

Hardware design engineers choose to utilise the plug and play nature of the Panasonic NaPiOn and PaPIR motion sensors in their actual product or in a remote monitoring module, to provide the reliable detection trigger.

Many IoT applications using PIR motion sensors are tending to require highly reliable detection rates and low power consumption by the sensor to enable battery powered operation. Obviously the the goal is to achieve maximum operating life before battery replacement is required. Only with absolute minimum power consumption by the sensor combined with optimised circuit design can extended battery life be achieved. PaPIR series sensors start from 1µA power consumption, meaning engineers have a powerful component at their disposal to save energy. This opens up even more areas of application.

As a conclusion - a system only works as reliably as the weakest link in the chain.

By using high-quality sensors, not only is the smallest link strengthened for the environment, but the electronics integrated into the sensor reduces the number of components overall. Extreme sensitivity and reliability, yet of miniature size, combined with low power consumption characterize modern PIR sensors and provide ways to save energy in almost every area of our daily lives.

Intelligent sensor technology not only helps save energy, it also improves safety and makes our lives more convenient. State-of-the-art technology allows sensors to be integrated into devices, making the devices more energy-efficient and easier to use, which profits the consumer. Passive infrared sensors (PIRs) offer many ways to save energy efficiently and easily.

 With all NaPiOn & PaPIR sensors having a standard 3 pin footprint , 2 pins for power supply and 1 pin for output signal, the circuit design once approved can use any of the 71 standard sensor variations depending on applications sensing / trigger requirements. This allows product designers to finalise hardware in reduced timescales and concentrate on the firmware/software offering of their application.

Panasonic offers a current motion sensor portfolio of 71 standard variants which cover detection ranges of 2 – 12 metres, number of detection beams per sensor 4 – 104, FOV 20degrees – 116 degrees, standard – slight – spot – long distance – dual zone lens types, analogue or digital output, plus a choice of 3 lens colours. There is continual development of new type which will be introduced during 2017.

Many projects succeed because Panasonic sensors allow for quick and easy product hardware development enabling engineers to work on the behavioural pattern modelling associated with their application.

Recent applications have included Wireless PIR modules for Smart Homes to assist with control of lighting, heating, ventilation and security, activating systems in the home for comfort & convenience of the occupier, whilst as a dual function powering down any system not necessary to run at 100%, thus saving energy consumption.

Further applications that are increasing in development based on IoT and behavioural modelling for the main purpose of energy saving in a commercial business environment is HOT-DESKING. Wireless PIR modules that are battery operated, monitor specific spaces for occupancy so that the Buildings Resource Management System can optimise allocation of building resources.

Due to their high performance and low cost, the NaPion and PaPir sensors are particularly suited to energy and security management applications including access control, door intercom systems, Intelligent light management, automatic control of air conditioning and ventilation systems, lighting in and around vending machines and public telephones and ATM’s.

Panasonic offer free technical support and product samples to allow designers with possible applications to fully evaluate the range of PIR products and decide on the most beneficial solution to their particular requirements.

I've worked for Panasonic Electric Works UK Limited for over 20 years, great in depth knowledge of many electro-mechanical switching products both theoretical and in live applications. Deal with both industrial and Automotive applications, including the rapidly growing Electric vehicle sector. Many of our products are available at RS components.
