Optical sensors - Ambient light, IR, UV Sensors convert the inputs of their respective light or heat into digital or analogue outputs. They are available in various surface mount and through-hole package types with a wide variety of wavelengths.
An optical sensor's primary function is to convert a light ray into an electronic signal. Depending on the sensor type, these sensors measure the physical amount of light and convert it into a readable form using an integrated measuring device.
What is an Ambient Light Sensor?
Ambient light sensors provide an optical power meter function inside the device. This optical sensor significantly improves the performance of the photodiode and photoresistor system. These sensors are ideal for detecting light or brightness, just like the human eye.
Uses
These sensors are often found in industrial lighting, consumer electronics, and automotive systems, where they allow automatic adjustment of device settings in response to changes in ambient lighting conditions. These sensors are available in different packages and are qualified for automotive standards.
What is an IR Sensor?
The IR sensor uses a range of wavelengths and a particular absorption layer so that infrared sensors can also function as large-area, long-lasting stable receivers of UV radiation. In addition, these sensors are bolometers and thermocouples, which also belong to thermal IR sensors.
UV Sensors
UV sensors measure the incident power or intensity of ultraviolet radiation. This form of electromagnetic radiation has a shorter wavelength than visible radiation but much longer than X-rays. These sensors determine exposure to ultraviolet radiation in the laboratory and environmental settings.
Applications of Optical Sensors - Ambient Light, IR, UV Sensors
These sensors are ideal for a variety of applications, including:
- Automobile Dashboard, Cameras, Cell Phones, Digital Picture Frames, Digital Signage, Displays & Infotainment, GPS, Laptops, LCD TVs.
- Commercial, Display Backlight Control, Keyboard, Medical Diagnostics, Printer Paper Detection
- Automotive Lighting, Light Sensing, Machine Vision, Security Lighting, Street Light Control
- MP3 players, PDAs, Video Recorders
- Display Backlight Control
- CCT, LED Lighting System.
