Spectra Flex Sensor 2.2 inch Bend Sensor for Hand Recognition
Spectra Flex Sensor 2.2 inch Bend Sensor for Hand Recognition
The Spectra Flex Sensor 2.2 inch is a resistive bend sensor designed for precise hand recognition and gesture detection. Its flexible substrate changes resistance linearly when bent, making it ideal for wearable electronics, robotics, and interactive installations. With a compact 2.2-inch sensing area, it integrates easily into gloves and controllers for real-time motion capture.

Compatibility
This flex sensor operates at 5V logic levels and interfaces directly with any analog-capable microcontroller. Common pairings include Arduino Uno, Mega, Nano, ESP8266, and Raspberry Pi Pico. It works with both 3.3V and 5V systems when using an appropriate voltage divider with a fixed resistor equal to the sensor's nominal resistance.
Wiring Notes
Connect one end of the sensor to VCC (5V or 3.3V) and the other end to a fixed 10K resistor to ground. The junction point goes to an analog input pin. No pull-up or pull-down resistor needed; the fixed resistor forms the divider. Avoid excessive bending beyond the minimum radius to prevent damage.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, it works with any Arduino board. Connect via a voltage divider to an analog pin and read the varying resistance as the sensor bends.
How many cycles can it withstand?
The Spectra flex sensor is rated for over 1 million bend cycles without significant drift, making it durable for repetitive applications.
Can I measure absolute angle?
It provides relative resistance change, so for absolute angle measurement you'll need to calibrate with known angles and map the analog values.
