Description

Long Flex/Bending Sensor 4.5″ (114mm)

The Long Flex/Bending Sensor 4.5″ (114mm) is a precision sensor designed to detect flexing, bending, and mechanical motion over a longer range. By converting physical bending into a measurable resistance change, it enables developers, hobbyists, and students to monitor motion, detect angles, or create interactive electronics projects.

With a length of 4.5 inches (114mm), this sensor is ideal for applications requiring extended bending measurement, such as wearable electronics, robotic joints, motion tracking systems, and DIY electronics prototypes. Its durable, flexible construction ensures consistent performance even after repeated bending cycles.

How the Long Flex Sensor Works

The Long Flex Sensor operates as a variable resistor. As the sensor bends, its resistance changes proportionally to the degree of flex, allowing microcontrollers to quantify motion or bending angles.

• Straight Position: Baseline resistance (commonly around 10kΩ).

• Bending: Resistance increases as the sensor flexes.

• Output Measurement: Connected to Arduino, Raspberry Pi, or ESP32, the resistance variation is read via analog input to detect motion or create interactive feedback.

This straightforward mechanism allows easy integration into projects for accurate and repeatable motion sensing.
