CJMCU-103 Rotary Angle Sensor Potentiometer 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. MCU-103 Rotation Angle Sensor has a dustproof design that protects the interior from dust, which maintains stable performance. It is compatible with high peak lead-free soldering. temperatures. Applications: Used in Switch for automotive, Motor drive unit, Radio control equipment, Electric motor-driven bicycle, etc

CJMCU-6701 GSR Skin Sensor Module Analog SPI 3.3V/5V The CJMCU-6701 GSR Skin Sensor Module is a biosensor module that measures the electrical conductance of the skin, also known as the Galvanic Skin Response (GSR). The module can be used to monitor changes in skin electrical conductance as a result of stress, emotions, or other physiological circumstances. This has a wide range of applications, including deception detection, human-computer interaction, and stress monitoring. The module is available in Analog, SPI, and 3.3V/5V versions, allowing it to be integrated into systems using 3.3V or 5V voltage and communicating with the microcontroller via the SPI protocol. The module is small in size and can be used in various other of applications. The working principle of the GSR sensor is based on the fact that the electrical conductance of the skin changes based on the level of sweat production. Sweat production is influenced by the level of emotional or physical arousal, thus changes in conductance can be used to infer changes in emotional or physiological states. GSR sensor clicks are ideally suited as an experimental tool for research, as well as for establishing effective test applications based on EDA reactions - such as polygraphs.
