Features 1,This is a force sensing resistor with a round, 1.27cm diameter, sensing area 2,This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance 3,This FSR can sense applied force on sensing area in the range of 0g-10kg 4,Two pins extend from the bottom of the sensor to mount the FSR 5,This sensor is simple to set up and great for sensing pressure, but you may not want to use it as a scale for it is not incredibly accurate Specification Features: This is a force sensing resistor with a round, 1.27cm diameter, sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. This FSR can sense applied force on sensing area in the range of 0g-10kg. Two pins extend from the bottom of the sensor to mount the FSR. This sensor is simple to set up and great for sensing pressure, but you may not want to use it as a scale for it is not incredibly accurate. Specifications: Sensing Area: 1.27cm or 0.5" Output Signal: Passive variable resistance Force Sensing Range: 0g-10kg Length: 6cm or 2.36" Width: 1.9cm or 0.75" Package Includes: 1 x Force Sensing Resistor Note: Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard. Package List Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
