ITEM NAME:Keyestudio Rotary encoder Analog Rotation Sensor module for Description: Its design is as a variable resistor, which could control motor speed. It also can measure angle with a simple pendulum wheel installed in its rotation head, rotating Angle from 0 to 300 degrees. This analog Rotation Sensor is compatible, it is based on a potentiometer. Its voltage can be subdivided into 1024, easy to be connected to with our sensor shield. Combined with other sensors, we can make interesting projects by reading the analog value from the IO port. Specification: Supply Voltage: 3.3V to 5V Interface: Analog Size: L 3.4 cm x W 2.9 cm x H 2 cm Material: FR - 4 epoxy glass fiber board Package Includes: 1 x Analog Rotation Sensor Module.1 x Analog Rotation Sensor Module. Combined with other sensors, we can make interesting projects by reading the analog value from the IO port. Interface: Analog. Car & Truck Parts. Decorations & Favours.
