APDS-9702-020 is an advanced position and motion sensing device developed and manufactured by Avago Technologies. It provides an ideal solution for applications that require accurate, reliable and cost-effective position and motion sensing. The APDS-9702-020 integrates a highly sensitive linear position sensor, an accelerometer and other motion sensing technologies to provide an ideal motion sensing solution with position information and motion sensing in one package.

APDS-9702-020 can be divided into two categories in terms of application fields: industrial and consumer electronics. Industrial applications mainly include motor position and speed control, robot arm position control, and angle and acceleration measurement in mechanical and aerospace systems. For consumer electronics, it is mainly used in the gaming and entertainment industry for device control, interactive gaming systems, and virtual reality systems.

The APDS-9702-020 has several unique features that can meet the needs of different applications. Its low power consumption and fast response time make it ideal for applications that require frequent and rapid position information updates. It also has excellent dynamic range and temperature characteristics, which can ensure accurate position and motion sensing even in harsh environments. Moreover, the device comes with various communication protocols, such as I2C, SPI, USB and UART.

The APDS-9702-020 uses the Hall effect principle to measure displacement, magnetostrictive force and acceleration. Its internal Hall sensor will detect the changes brought by the displacement of the movable magnetic body, and convert the changes into an electrical signal proportional to the magnitude of the magnetic field. The analog signal is then converted into a digital signal through the ADC, and the displacement or acceleration is calculated. On the other hand, it also uses magnetostriction to measure acceleration. The device features an optical fiber connected to a Piezoelectric Crystal. When the device is accelerated, the Piezoelectric crystal generates a voltage proportional to the magnitude of acceleration, which is then converted into a digital signal and measured. The device can then detect the magnitude of acceleration and calculate the displacement accordingly.

To sum up, APDS-9702-020 is a versatile motion sensing device with excellent performance and high accuracy. It has a wide range of applications in both industrial and consumer electronics fields and its cost-effectiveness makes it an ideal solution for motion sensing applications. With its low power consumption and fast response time, the APDS-9702-020 offers high reliability and accuracy for position and motion sensing.
