Point-of Sale (POS) System - Secure keypads for payment terminals and self-service kiosks. Matrix Keypad - Functionality & Connection Overview   A 4x4 matrix keypad operates using a structured combination of four rows and four columns, providing efficient button state detection for microcontrollers and host devices. Each key contains an embedded push-button switch, where one terminal is connected to a row and the other to a column. How It Works ?   The microcontroller scans the keypad by sequentially pulling each of the four column pins (1-4) HIGH or LOW while monitoring the state of the four row pins (5-8). When a key is pressed, it completes a circuit between a specific row and column, enabling the microcontroller to identify the exact key pressed. This method ensures an efficient, low-power, and interference-free way to register key inputs.

FSRs are sensors that allow you to detect physical pressure, squeezing and weight. They are simple to use and low cost.FSRs are basically a resistor that changes its resistive value (in ohms Ω) depending on how much it is pressed. These sensors are fairly low cost, and easy to use but they're rarely accurate. They also vary some from sensor to sensor perhaps 10%. So basically when you use FSRs you should only expect to get ranges of response.

Flexible Heaters   Flexible Printed Heaters are simple warming elements that are screen printed on flexible materials. Through careful control of design elements and the deposition of functional inks, flexible printed heaters can be made to specific operating parameters and can be customized according to user requirements. Conventional heaters are heavy to transport, take up space, and can also fail due to faulty wires or coils. Printed heaters can be a solution to all these problems. Printed heaters are used in heated garments, automotive and medical applications, etc. Key Features of Flexible Heaters:   Flexibility: Designed to bend and conform to complex shapes, allowing integration into diverse applications. Thin Profile: Typically, very thin, minimizing space requirements and enabling use in compact assemblies. Uniform Heating: Provide consistent heat distribution across the surface, enhancing performance. Customizability: Available in various shapes, sizes, and watt densities to meet specific application needs. Rapid Response Time: Quickly reach operating temperatures, improving process efficiency. Common Specifications:   Temperature Range: Operating temperatures can vary; for instance, silicone rubber heaters can operate up to 232°C (450°F) , while polyimide (Kapton) heaters typically operate up to 200°C. Watt Density: Standard watt densities range from 2.5 W/in² to 10 W/in², with custom options available for specific requirements. Thickness: Generally between 0.01 inches (0.25 mm) and 0.03 inches (0.76 mm), depending on the material and construction. Voltage: Available in various voltage ratings, commonly from 12V to 480V, to suit different power supply configurations. Sizes: Can be manufactured in sizes ranging from small dimensions (e.g., 10 mm x 10 mm) up to large areas (e.g., 2 ft x 3ft) , depending on the application. Material Selection   Heater Element: Typically made from materials like conductive inks that can generate heat when an electric current passes through. Substrate: For window heaters, a transparent material like glass with conductive elements printed or embedded in it is used. For seat heaters, flexible materials like carbon fiber are common. Adhesives and Insulators: For proper installation, heat-resistant adhesives and electrical insulators are required to ensure safety and durability. Application   Medical Devices: Maintaining patient temperatures, warming intravenous fluids, and blood analyzers. Aerospace: De-icing equipment, temperature control of instruments, and satellite components. Electronics: Preventing condensation in enclosures, battery warming, and ensuring optimal operating temperatures for components. Automotive: Seat heaters, mirror defoggers, and battery warming systems.
