Short Flex/Bending Sensor 2.2″ (56mm)

The Short Flex/Bending Sensor 2.2″ (56mm) is a high-precision, durable sensor designed to detect flexing, bending, and mechanical motion in a wide range of applications. Compact and easy to use, this sensor converts physical bending into a measurable change in resistance, enabling you to track motion, detect angles, or create interactive electronic projects.

With its 56mm length (2.2 inches), this short flex sensor is perfect for projects requiring compact design, such as wearable electronics, robotics, motion-sensitive devices, and DIY electronics prototypes. Its simple operation, reliable performance, and broad compatibility make it a favorite choice for hobbyists, students, and professional developers alike.

How It Works

The flex sensor functions as a variable resistor. When the sensor bends, its electrical resistance changes proportionally to the angle of the bend. By connecting it to a microcontroller or analog input device, you can measure the degree of bending and incorporate it into software to create responsive systems.

Typical operation involves:

• Straight Position: Low baseline resistance (usually around 10kΩ for standard models).

• Bending: Resistance increases as the sensor is flexed.

• Output Measurement: Microcontrollers such as Arduino, Raspberry Pi, or ESP32 read the resistance change via analog pins.

This simplicity makes it an excellent choice for beginners learning about sensors and analog electronics.
