Introduction to ADNS-6090 Optical Sensors

The ADNS-6090 optical sensor by Avago Technologies is a miniaturized mouse sensor system used in a variety of applications. Featuring an on-board 16-bit 6800 microcontroller, it is capable of capturing up to 8 million frames per second of movement data. It is a versatile sensor that can be used to detect both ambient light levels and object motions, with a sensing range of up to 0.25 millimeters per second on the X-Y axes.

Ambient Light Capability

The ADNS-6090 is an ideal optical sensor for ambient light applications. It is able to accurately measure the intensity of visible or infrared light from 30uW/m2 up to 30mW/m2. This makes it suitable for applications such as auto-dimming and automotive lighting systems that require precise ambient-light detection. Additionally, the sensor also features two separate gain settings, allowing for changes in sensitivity for different light levels.

IR and UV Sensing

The ADNS-6090 can also be used in applications that require sensing of infrared and ultraviolet radiation. It is sensitive to light in the 850nm to 1050nm wavelength range, meaning it can detect light emitted by IR-emitting diodes, as well as UV-emitting LEDs, such as those used in medical and security applications. With its highly sensitive light detection technology, it can detect light levels up to 20x lower than most other sensors.

Working Principle

The ADNS-6090 is based on a light eyetracking technique, where the intensity of the beam is measured when it is deflected from an object. The sensor is composed of a compact package housing an infrared LED, a light lens, and two photodiodes mounted on a spring-loaded MEMS mirror. When an object is detected by the sensor, the mirror will deflect the beam of light from the LED, which then reflects off the object and is captured by the two photodiodes. The photodiodes then convert the light signal into an electrical signal, which is then processed by the on-board microcontroller to identify the object and measure its movement.

Conclusion

The ADNS-6090 optical sensor from Avago Technologies offers an array of features that make it an ideal choice for a variety of sensing applications. It is capable of capturing ambient light levels, as well as sensing infrared and ultraviolet wavelengths, making it a versatile and highly sensitive optical sensor. Additionally, its light eyetracking technology allows it to track the movement of objects with unprecedented accuracy. With its highly sensitive light detection technology, as well as its powerful on-board processing capability, the ADNS-6090 is a reliable and robust optical sensor for a wide range of applications.
