Smart Electronics High density distribution plantar pressure sensor, resistor type sensor FSR pressure acquisition weight sensor

High density distribution plantar pressure sensor, resistor type sensor FSR pressure acquisition weight sensor Film pressure sensor is piezoresistive, also known as resistive, equivalent to varistor in the circuit. When the sensor has no external load, the circuit is in high resistance state (generally greater than 2m Ω). When the external pressure is applied to the sensor, the circuit resistance will decrease (tens of K Ω or less). With a multimeter, the resistance value can be read directly by connecting to two external terminals. The resistance value changes with the change of external pressure. The voltage is inversely proportional to the resistance, while the voltage カ is linearly related to the conductivity, so the pressure change can be inversely deduced according to the conductivity change.

Smart Electronics FSR406 Pressure Sensor , 100% New and Original Force Sensitive Resistor

FSR406 Pressure Sensor , 100% New and Original Force Sensitive Resistor This is a force sensitive resistor with a square, 1.75x1.5", 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. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg.
