Product application
In the smart watch heart rate monitoring module, the resistor provides a stable working environment for the sensor. The bias resistor provides the appropriate bias voltage for the photoelectric sensor, so that the sensor can accurately detect changes in light intensity in the blood, thereby accurately calculating the heart rate. Resistors are also used in signal conditioning circuits to process weak signals output by sensors.
In the gamepad button circuit, the pull-down resistor is used to eliminate button jitter. When a key is pressed or released, due to mechanical structure reasons, a brief level instability will occur, that is, key jitter. The pull-down resistor stabilizes the button signal line at a low level when the button is not pressed. When the button is pressed, the signal line is pulled to a high level.
In the Bluetooth speaker volume control circuit, the potentiometer is used as an adjustable resistor to adjust the audio signal amplitude by changing the resistance of the access circuit. Turn the potentiometer knob, and its moving piece slides on the resistor body, changing the ratio of the upper and lower voltage dividing resistors, thereby changing the voltage of the output audio signal and achieving stepless adjustment of the volume. same
In the digital camera flash trigger circuit, the resistor plays the role of current limiting and protection. At the moment of triggering, a large current will be generated in the circuit. The current-limiting resistor can effectively limit the size of the current and prevent excessive current from damaging the flash tube, transistors and other components in the trigger circuit. At the same time, the resistor participates in the formation and transmission of the trigger pulse
