This small force sensitive resistor is a great choice for pressure sensing. It features a 0.16' (4 mm) diameter active sensing area. The resistance of this FSR changes based on the pressure applied to the sensing area - the harder the force, the lower the resistance. When no pressure is applied, its resistance is larger than 1MΩ, and with full pressure, it drops to 2.5kΩ. Two pins extend from the bottom of the sensor with a 0.1' pitch, making it easy to use with a breadboard. These sensors are simple to set up and are good for detecting if something is being squeezed, though they aren't highly accurate for precise measurements like a scale. SPECIFICATIONS: Overall length is 1.75', overall width is 0.28', and the sensing area is 0.3'. DOCUMENTS: FSR Integration Guide and FSR Tutorial. SHIPPING LIST: One Compact Force Sensitive Resistor.
Using this force sensitive resistor is quite easy. First, connect the two pins on the bottom of the sensor to your circuit on a breadboard. When you want to sense pressure, just apply force to the sensing area. The resistor will change its resistance according to the pressure. As a tip, don't rely on it for very accurate measurements like a weighing scale. It's better for just detecting if something is being squeezed. For maintenance, keep it in a dry place and avoid applying excessive force that could damage the sensing area. If you have any questions about integrating it into your project, refer to the FSR Integration Guide and FSR Tutorial provided.
