The Person Sensor: A Standalone Intelligent Device
In the world of edge computing, having standalone intelligence is crucial. That's where the Person Sensor comes in. This compact and easy-to-use device is designed to detect the presence of a person with high accuracy and reliability. In this article, we will explore the functionality and advantages of the Person Sensor, as well as its various applications.
Introduction
In today's increasingly connected world, the demand for intelligent devices that can operate independently on the edge is growing rapidly. These devices need to be able to perform tasks and make decisions without relying on constant connectivity to the cloud. The Person Sensor is an innovative solution that addresses this need. It is a standalone intelligent device that can detect the presence of a person with remarkable precision.
The Person Sensor: A Standalone Intelligent Device
The Person Sensor is a revolutionary device that combines advanced technology with a user-friendly design. It is built on the concept of a Person Infrared (PIR) sensor but with significant improvements. Unlike traditional PIR sensors that can be triggered by any movement, the Person Sensor only activates when it detects the presence of a person. This eliminates false alarms caused by animals, trees, or inanimate objects.
How the Person Sensor Works
The Person Sensor operates Based on a simple principle. It has a single Pin that goes high when it detects the presence of a person. This pin can be easily connected to other devices or systems for further processing or action. Additionally, the Person Sensor features an I2C interface, allowing it to provide valuable information about the person detected, such as their proximity to the device and even facial recognition data.
Advantages of the Person Sensor
The Person Sensor offers several advantages over traditional PIR sensors. Firstly, it provides accurate and reliable detection of human presence, ensuring that it is only activated when needed. This saves energy and minimizes false alarms. Secondly, the I2C interface enables advanced functionalities like facial recognition, making it suitable for applications that require more than just presence detection.
Philips Hue Lighting Demo: An Application of the Person Sensor
One of the applications that showcase the capabilities of the Person Sensor is the Philips Hue Lighting Demo. This demo highlights how the device can be used to control smart lighting systems based on the user's presence and gaze direction. By combining the Person Sensor with a speech sensor for natural language processing, users can Interact with the lighting system simply by looking at it and giving commands.
Face-Following Fan: Another Application of the Person Sensor
Another interesting application of the Person Sensor is the face-following fan. By utilizing the person detection capabilities of the sensor, this fan can track the user's face and direct cool air towards them. This ensures that the user always receives a comfortable airflow, enhancing their overall experience.
Speech Recognition Demo: Utilizing the Speech Sensor
In addition to person detection, the Person Sensor can also be combined with a speech sensor to enable speech recognition functionality. This demo showcases how users can speak commands to control devices equipped with the Person Sensor. The device only listens to commands when the user is actively looking at it, ensuring optimal accuracy and privacy.
Availability of the Person Sensor
The Person Sensor is currently available for purchase, with the V1 version released in October. It can be found on popular electronic component marketplaces such as DigiKey and SparkFun in the U.S. Additionally, the company plans to release newer sensor models in the near future, expanding the range of available options for customers.
Modules vs. Customization: Choosing the Right Option
When it comes to utilizing the Person Sensor, customers have the option to either use pre-built modules or customize the sensor for their specific requirements. While modules offer a quick and easy way to get started, they may not always meet specialized needs. In such cases, working with companies like Edge Impulse can provide the expertise needed to design custom models for unique applications.
Challenges in Miniaturizing the Device
Miniaturizing the Person Sensor presented several challenges during its development. In terms of hardware, sourcing tiny components and dealing with supply chain issues proved to be complex tasks. Additionally, optimizing cost while maintaining functionality was a significant consideration. These challenges required collaboration between software and hardware engineers to overcome successfully.
Challenges in Implementing Artificial Intelligence in a Small Package
Implementing artificial intelligence in a small, low-power package had its own set of challenges. However, the team behind the Person Sensor had prior experience in this area, having worked on similar projects at prestigious companies like Google. Therefore, squeezing AI models into microcontrollers was a relatively straightforward process. The real difficulties lay in other aspects, such as hardware design and manufacturing.
TinyML: A Growing Community of Tiny Machine Learning
The concept of TinyML emerged as a result of the need to deploy machine learning models in embedded systems. It refers to the process of shrinking complex models to fit the constraints of tiny devices. The Person Sensor is an example of how TinyML can be applied practically. Over the years, a vibrant community has formed around TinyML, sharing knowledge and pushing the boundaries of what can be achieved with small-Scale machine learning.
