# 3-Pin / ADI Sensors

- [Encoder](https://wiki.purduesigbots.com/vex-electronics/vex-sensors/3-pin-adi-sensors/encoder.md): The VEX Encoder helps to determine the rotation of a shaft.
- [Potentiometer](https://wiki.purduesigbots.com/vex-electronics/vex-sensors/3-pin-adi-sensors/potentiometer.md): The VEX Potentiometer helps track the rotations of shafts
- [Limit Switch](https://wiki.purduesigbots.com/vex-electronics/vex-sensors/3-pin-adi-sensors/limit-switch.md): The Limit Switch is a sensor that returns a value when it is pressed.
- [Bumper Switch](https://wiki.purduesigbots.com/vex-electronics/vex-sensors/3-pin-adi-sensors/bumper.md): The Bumper Switch returns when the switch is pressed.
- [Accelerometer](https://wiki.purduesigbots.com/vex-electronics/vex-sensors/3-pin-adi-sensors/accelerometer.md): An Accelerometer measures proper acceleration.
- [Gyroscope](https://wiki.purduesigbots.com/vex-electronics/vex-sensors/3-pin-adi-sensors/gyroscope.md): The VEX Yaw Rate Gyroscope returns the rate of rotation around the vertical axis.
- [Ultrasonic](https://wiki.purduesigbots.com/vex-electronics/vex-sensors/3-pin-adi-sensors/ultrasonic.md): The VEX Ultrasonic Range Finder helps determine how far away an object is.
- [Line Tracker](https://wiki.purduesigbots.com/vex-electronics/vex-sensors/3-pin-adi-sensors/line-tracker.md): The Line Tracker can track "lines" and other objects using infrared LEDs
- [LED Indicator](https://wiki.purduesigbots.com/vex-electronics/vex-sensors/3-pin-adi-sensors/line-tracker-1.md)
