FlexiForce Pressure Sensor - 25lbs (1 area)

This Tekscan piezoresistive force sensor is a remarkable device. The harder you press, the lower its resistance gets. When you press firmly, the resistance shifts from infinite to about 50k. It's thin and flexible, but the resistance only changes when pressure is applied to the round area at the sensor's end, not when it's flexed. It can be used as a presence sensor (to detect someone standing), a weight sensor, or for pressure testing in impact scenarios. The sensor is about 2.25' long and comes with a 0.1' spaced, reinforced, breadboard - friendly connector. It can measure pressure ranging from 0 to 25lbs. There are several useful documents available, including a datasheet (ZFLEX A401 - 25), a product page, a Bildr tutorial, and a quickstart guide.

Using this Tekscan FlexiForce pressure sensor is easy. First, connect it to your device using the 0.1' spaced, reinforced, breadboard - friendly connector. You can use it to detect if someone is standing by placing it on the ground. Or, use it for weight or pressure testing in impact scenarios. Remember, the resistance only changes when you apply pressure to the round area at the end of the sensor, so make sure the pressure is applied there. Don't bend it too forcefully, as it may damage the sensor. To maintain it, keep it clean and dry. When not in use, store it in a safe place away from sharp objects. Refer to the datasheet (ZFLEX A401 - 25) and quickstart guide for more detailed information.
