Short Flex Sensor
₱750.00
Description:
This simple, short flex sensor, 2.2" in length, can detect flexing or bending in one direction. They were popularized by being used in the Nintendo PowerGlove as a gaming interface.
These sensors are easy to use; they are basically resistors that change value based on how much they are flexed. If they're unflexed, the resistance is about ~25KΩ. When flexed all the way, the resistance rises to ~100KΩ. You can use an analog input on a microcontroller (with a pullup resistor) or a digital input with the use of a 0.1uF capacitor for RC timing. The resistance of the sensor changes when the metal pads are on the outside of the bend (text on the inside of the bend).
The bottom part of the sensor (where the pins are crimped on) is very delicate, so make sure to have strain relief, such as clamping or gluing that part, so as not to rip out the contacts!
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 sensor to flex.
