Detailed Description:

Unlock intuitive, physical interaction for your electronic projects with the Flex Sensor - 2.2 Inch Bend Sensor. This high-quality component is an indispensable tool for a wide range of innovative applications, from creating natural hand gesture recognition systems to building responsive robotics and advanced wearable tech with your Arduino board. As the sensor is physically bent or flexed, its internal resistance changes, providing a direct and continuous measurement of the degree of flexion.

Functioning as a variable resistor, the Flex Sensor is easily interfaced with your Arduino via a simple voltage divider circuit. By connecting it in series with a fixed resistor (typically 10kΩ), you can convert the sensor's changing resistance into a readable analog voltage. This voltage can be fed directly into an analog input pin on an Arduino Uno, Mega, or other compatible development board. The microcontroller's Analog-to-Digital Converter (ADC) then translates this voltage into a digital value (0-1023), allowing you to precisely quantify the amount of bend. The 2.2-inch version is perfectly sized for fitting along a finger or a small robotic joint.

When straight, the sensor has a nominal resistance (e.g., around 10kΩ to 30kΩ). As you bend it, the resistance increases, often reaching two or three times its initial value at a 90-degree angle. This repeatable and durable design, rated for over a million flex cycles, makes it a reliable choice for long-term projects. With its straightforward use and powerful capabilities, the 2.2-inch Flex Sensor is a fundamental component for adding smart motion and gesture detection to your creations. Whether you're a student working on a college project or a hobbyist in Pune, Maharashtra, India, this sensor is a must-have for bringing your ideas to life.

The 2.2″ Flex Sensor is a flexible resistor strip that varies its resistance as it is bent. In the flat (unflexed) position, the sensor has a baseline resistance (~10KΩ). As the strip is bent, the resistance increases proportionally to the bend angle.

Commonly used in hand gesture gloves, robotic arms, and wearable electronics, this sensor is compatible with Arduino, ESP32, and Raspberry Pi. You can interface it using a voltage divider circuit and measure changes via analog input.

Its compact size, ease of use, and long bending life make it suitable for a wide range of biometric and human interface device (HID) applications.
