Item Type: Flexible Force Sensing Resistor Output Type: Resistive, voltage Output Voltage: 3.3 Material: Semiconductor Accuracy: 10% Working Temperature: 25 () Package Case: PET How to Use: 1. The flexible pressure and temperature integrated sensors are nonpolarity components and have no directionality in the circuit; 2. When using, please place the pressure sensitive area of the sensor on a firm and flat surface. Using the sensor on a curved or special shaped surface will make the sensor initially conductive, that is, will be in a "response" state when there is no pressure; in this state, the output resistance of the sensor can still respond to pressure changes, and the corresponding relationship is no longer applicable to the reference data sheet; 3. If both the support surface and the force application surface are rigid and hard surfaces, and the contact surface is larger than the sensitive area of the sensor, due to the structure of the sensor itself, the pressure response may be small and unstable. A circular soft rubber pad needs to be attached to the center of the sensitive area, the diameter is slightly smaller than that of the sensitive area, and the area should be larger than 60% of the area of the sensitive area; 4. You can use double sided tape to fix the sensor on the support surface, pay attention to the neatness and cleanliness of the support surface before sticking. Double sided recommended glue; 5. After the sensor is stressed and maintains the pressure, the output resistance value will drift slightly over time, usually within 5%. can be determined by time calibration method reduces this error. In the calibration operation, the waiting time for stabilization after applying pressure is consistent with the waiting time in practical applications. Since the stress state of the sensor is different in different application scenarios, it is recommended that the user arrange the sensor according to the actual application scenario and test out the drift parameters by himself. 6. Please use the sensor within the specified operating temperature.
