General Description

The US1881 is a bipolar Hall effect sensor IC fabricated from mixed signal CMOS technology. It incorporates advanced chopper
stabilization techniques to provide accurate and stable magnetic switch points. There are many applications for this HED in addition to
those listed above. The design, specifications and performance have been optimized for commutation applications in 5V and 12V brushless DC motors.

The output transistor will be latched on (BOP) in the presence of a sufficiently strong South pole magnetic field facing the marked side of the package.
Similarly, the output will be latched off (BRP) in the presence of a North field. The SOT-23 device is reversed from the UA package.

The SOT-23 output transistor will be latched on in the presence of a sufficiently strong North pole magnetic field applied to the marked face.

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.

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.
