In our increasingly interconnected world, the adoption of reliable, effective sensors has become a must for many electronic manufacturing companies. Leading this technological revolution is PixArt Imaging, a renowned manufacturer of CMOS imaging sensors and navigation related integrated chipsets. Incorporating PixArt's advanced sensing solutions into your next coffee machine can help to make it highly intuitive, capable of recognizing cup sizes, volumes, coffee pod types, and maintaining optimal brewing temperature.
User Control Interfaces
At the core of any efficient coffee machine lies the User Control Interface. PixArt’s Capacitive Finger Navigation solution, PCT1812FF, excels in this area. Providing high sensitivity with oil and water immunity, this solution has robustness perfect for the coffee machine environment. With its low power consumption and capability to support up to 36 buttons, it boasts specs crucial in enhancing user control in coffee machines.
A unique feature of the PCT1812FF is the glove touch support under 6mm Acrylic and 1cm glass. Its small module size encapsulated in a QFN20, 4x4 case and its easy connectivity over the I2C bus make it a great addition to appliance engineering projects.
Enhancement to PixArt's primary User Control Interface, the Single Object Gesture Sensor PAG7631J2 is a highly integrated module with Gesture sensor, Lens & LED in one device. Housed in a compact 9.7 x 4.7 x 2.75mm³ reflowable case, it not only integrates a built-in light source, which can operate in total dark environment, but also an ambient light rejection filter, in order to reduce ambient light interference. The module comes with 10 pre-defined gestures, and operating distances up to 30cm. This intuitive Gesture Sensor gives engineers the tools to create a more interactive and user-friendly coffee machine.
Non-contact Temperature Sensing
Additionally, maintaining precision in water or coffee temperature plays a significant role in any sophisticated coffee machine design. PixArt's PAF9614 non-contact thermal FIR sensor addresses this requirement. With a response time of less than 0.25 seconds, it ensures accurate temperature detection for both water and coffee. Using a temperature compensated algorithm its accuracy is greater than +/-2⁰C between 85⁰C and 95⁰C (or Fahrenheit). This is an absolute must-have feature to create the perfect brew.
Cup and Volume Recognition
PixArt’s PAC7088J4 aids in pinpointing the coffee cup and volume detection. It’s a compact-size single-axis distance sensor module, with a maximum sensing distance of 20cm. It includes an embedded flash to customize object sensing characteristics. With an 103° view angle, and an ability to sense obstacles between 2cm-20cm, this component indeed adds more intuition to a smart coffee machine design.
Advanced Image Processing
PixArt’s ultra-low power CMOS image sensor (PAG7920J1) and deep learning engine (PAG7681LS) offer advanced image processing solutions. The sensors bring forth features such as low power consumption, a resolution of 320x240, and a choice of an image interface in Parallel or SPI formats. PixArt's PAG7681LS, on the other hand, enhances object detection processing with an embedded deep learning MCU for flow control.
Combining deep learning on the edge instead of on the cloud resulting in increased privacy, security, and real-time outputs of detected object information. This combination helps boost the intelligence and responsiveness of the coffee machine.
