CJMCU-103 Rotary Angle Sensor module

The CJMCU-103 is a rotary angle sensor module that measures the angular position of a shaft or other rotating object using a potentiometer. A potentiometer is a sort of variable resistor that can be used to measure a shaft’s location by altering the resistance as the shaft rotates. A potentiometer is commonly attached to the shaft, and an integrated circuit (IC) turns the potentiometer’s resistance into a voltage or digital signal that can be read by a microcontroller or other device.

The CJMCU-103 is a low-power, compact device with a wide range of system integration options. It can be used to calculate the angle of a steering wheel, regulate the movement of a robot arm, or detect the angular location of a motor shaft.
