Spectra Symbol Flex Sensor 2.2 FS-L-0055 for Hand Gesture

Spectra Symbol Flex Sensor 2.2 FS-L-0055 for Hand Gesture Recognition or bend sensor is a sensor that measures the amount of deflection or bending.

Usually, the sensor is stuck to the surface, and resistance of sensor element is varied by bending the surface.

A Spectra Symbol Flex Sensor 2.2 is a kind of sensor which is used to measure the amount of defection otherwise bending.

The designing of this sensor can be done by using materials like plastic and carbon. The carbon surface is arranged on a plastic strip as this strip is turned aside then the sensor’s resistance will be changed.

The easiest way to read the flex sensor is to connect it with a fixed value resistor (usually 47kΩ) to create a voltage divider. To do this you connect one end of the sensor to Power and the other to a pull-down resistor.
The Spectra Symbol Flex Sensor 2.2 is a unique component that changes resistance when bent. An unflexed sensor has a nominal resistance of 10,000 ohms (10 K).

As the flex sensor is bent the resistance gradually increases. When the sensor is bent at 90 degrees its resistance will range between 30-40 K ohms.

Spectra Symbol Flex Sensor 2.2 for Hand Gesture Recognition are common in different technological products, such as automotive and industrial controls, computer peripherals, joysticks, and measuring devices.

These are also present in fitness products, musical instruments, and assistive technology systems of modern vehicles.

Flex sensors are available in two sizes: one 2.2″ (5.588cm) long and another coming in at 4.5″ (11.43cm) long. Left flat, these sensors will look like a 30kΩ resistor.

As it bends, the resistance between the two terminals will increase to as much as 70kΩ at a 90° angle.

Note: –

Please refrain from flexing or straining this sensor at the base. The usable range of the sensor can be flexed without a problem, but care should be taken to minimize flexing outside of the usable range. For best results, securely mount the base and bottom portion and only allow the actual flex sensor to flex.
