LEDs As Light Sensors : 5 Steps - Instructables

LEDs are great for making light, but they can sense light too! I recently stumbled upon this site which mentions, "In 1977, Forrest M. Mims reminds us in one of his "Engineer's Notebooks" that LEDs can also be used as photodiodes... " The page features a LED matrix being used as a multi-touch input but offers very little information.

VOC Sensors and Monitors - Volatile Organic Compounds

Aeroqual offers two types of VOC measurement sensors; Photoionization Detector (PID), and Gas Sensitive Semiconductor (GSS). Both sensor types are non-selective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a calibrated measurement range against a set of VOCs. PID type VOC sensors are more resilient and can ...

Activity: LED as light sensor [Analog Devices Wiki]

In addition to emitting light, an LED can be used as a photodiode light sensor / detector. This capability may be used in a variety of applications including ambient light level sensor and bidirectional communications. As a photodiode, an LED is sensitive to wavelengths equal to or shorter than the predominant wavelength it emits. A green LED would be sensitive to blue light and to some green ...
