Force Sensor Arduino FSR 402 Description:

• FSR402=FA402,FSR408=FA408,FSR502=FA502 0.5 inch Pressure Sensor Resistance Stress Test Force Sensing Resistor for Arduino DIY: Kit
• This pressure sensor converts the  pressure apply in the thin film area of the FSR sensor into the change of resistance value, so as to obtain pressure information.
• The higher the pressure, the lower the resistance.
• It is allow to be use at pressure of 100g-10kg.
• It can be us in the end gripper of the manipulator to sense the presence or absence of gripping objects, the foot of the bionic robot to walk on the ground, and has a wide range of applications.
• Sensing area (Sensing range) : 0.5 “circle
  The Output signal (Output signal) : Passive variable to hold
  The Force sensitive range (range), pressure test: 100 g to 10 kg
  Lifetime (life) : > 10 m letters actuations
  Dimensions:
  Overall length: 2.375″
  Overall width: 0.75″
  Sensing the diameter: 0.5”

• Force Sensor Arduino FSR 402 Description:

• 
• This force-sensing resistor (FSR) from Interlink Electronics is a passive component that exhibits a decrease in resistance when there is an increase in the force apply to the 0.58″-diameter (1.5 cm) active area
• With a force sensitivity range of a few grams to a few kilograms, this sensor is optimize for use in human touch control applications
• This force-sensing resistor (FSR) from Interlink Electronics is a passive component that exhibits a decrease in resistance when there is an increase in the force apply to the 0.58″-diameter (1.5 cm) active area, allowing you to create a sensor that is able to detect force or pressure. With a force sensitivity range of a few grams to a few kilograms, this sensor is optimize for use in human touch control applications.
