Flex Sensor 4.5″

Flex Sensor 4.5 Inch Price in Pakistan

The 4.5-inch flex sensor is a thin variable resistor for measuring relative bend in wearables, robotics, motion controls and interactive electronics. Its resistance increases as the active strip bends, allowing a microcontroller to monitor movement through a voltage-divider circuit and analog input.

How to use the flex sensor

• Pair the sensor with a fixed resistor to create a voltage divider.
• Read the divided voltage with a compatible analog input.
• Record the relaxed and intended maximum-bend readings.
• Map the calibrated range to the required control value in software.

The sensor is designed for bend detection rather than direct pressure or weight measurement. Mount the base securely, bend only the active length and avoid sharp creases or strain at the connector. Electrical response varies with bend radius, mounting method and component tolerance, so application-specific calibration is essential.

For analog bend experiments, pair the sensor with an Arduino UNO R3 and a suitable fixed resistor, then calibrate the completed wearable or control assembly.
