This piezoresistive force sensor is a great tool for various applications. As you press harder, its resistance drops. When pressed firmly, the resistance shifts from infinite to around 300k. The sensor is thin and flexible, but flexing it won't change the resistance. Resistance changes only when pressure is applied to the round area at the end. It can be used as a presence sensor to detect someone standing, a weight sensor, or for pressure testing in impact scenarios. It comes in three types and can measure pressure from 0 to 100lbs in the mega - ohm range. The sensor has an overall length of about 8.5'. It features a 0.1' spaced, reinforced, breadboard - friendly connector. Applications include detecting and measuring relative force changes, force change rates, identifying force thresholds, and detecting contact or touch. Specifications are impressive with greater flexibility, a response time of less than 5 ms, a 0 - 100lbs (440 N) detect range, a 3 - pin male square pin connector, a 9.53mm (0.38') diameter sensing area, a max working current of 2.5mA, and a size of 216x14mm (8.5x0.55'). You'll also get access to a datasheet, user manual, and the Flexiforce homepage. The shipping list includes one 100lbs Flexiforce Pressure Sensor.
Using this Flexiforce pressure sensor is easy. First, connect it to your device using the 3 - pin male square pin connector. When you want to measure pressure, make sure the pressure is applied to the round area at the end of the sensor. You can use it to detect if someone is standing on it, measure weights, or for impact testing. For best results, keep the working current below 2.5mA. When handling the sensor, be gentle as it's thin and flexible, though flexing it won't affect the resistance measurement. To maintain it, store it in a dry and clean place. Don't expose it to extreme temperatures or excessive humidity. Regularly check the datasheet and user manual for any updated information on usage and maintenance.
