The Flex Sensor 4.5" china is a basic bend sensor that detects physical movement and translates it into variable resistance output. As the sensor flexes, the internal carbon elements respond by increasing resistance, enabling precise angle displacement measurements. Designed to operate in a wide temperature range from -35°C to +80°C, this sensor is suited for fields like robotics, gaming, medical instrumentation, musical interfaces, and physical therapy devices. Trusted by industry pioneers and once featured in the Nintendo Power Glove. Featured By RoboticsBD.

Before we get to circuit-building and Arduino-programming, here's a quick rundown of the flex sensor's important electrical characteristics.
How it Works
When the sensor straightens out again, the resistance returns to the original value. By measuring the resistance, you can determine how much the sensor is being bent.
The flex sensor is designed to be flexed in just one direction – away from the ink – as demonstrated in the image below.

Bending the sensor in the other direction will not produce any reliable data, and may damage the sensor. Also take care not to bend the sensor close to the base, as they have a tendency to kink and fail.
