Flex Sensor 2.2 Inch Bend Sensor for Arduino, ESP32 & Robotics
The Flex Sensor 2.2 Inch is a highly sensitive bend sensor designed to detect changes in resistance when bent. It is widely used in robotics, wearable electronics, prosthetic hands, gesture recognition systems, gaming controllers, and Arduino-based automation projects. Its lightweight and flexible construction makes it ideal for educational, research, and industrial applications.
Whether you are a Bangladeshi student building your first Arduino project or an engineer developing advanced motion detection systems, the 2.2-inch Flex Sensor offers reliable analog output for accurate bend measurement.
The 2.2 Inch Flex Sensor changes its electrical resistance according to the amount of bending applied. When the sensor remains straight, its resistance stays at its nominal value. As the sensor bends, the resistance increases proportionally, allowing microcontrollers such as Arduino, ESP32, STM32, Raspberry Pi Pico, and Raspberry Pi (via ADC) to measure the bending angle.
This sensor is commonly used in:
- Robotic hand projects
- Motion sensing
- Human-machine interface (HMI)
- VR and gaming controllers
- Smart gloves
- Medical rehabilitation devices
- Gesture-controlled robots
- Finger movement detection
- Wearable electronics
- STEM education projects
Its simple analog interface makes integration easy with most development boards.
