How UV, IR and Imaging Detectors Work - Sensor Technology

An IR detector is a pyroelectric sensor that is capable of detecting thermal radiation and is rather sensitive to variations of the received light signal. A tantalum/lithium crystal is associated with an OP amp or a field-effect transistor. An optical filter (a spectral gate) chooses a specific spectral band or wavelength ( µm, µm, 4 to 5 µm…). The crystal perceives the random ...

IR Sensor to detect color | Microchip

· By definition, an IR sensor detects one specific color, infra-red, so it doesn't seem a good choice to detect black and white.. Could you explain a bit more about what you are actually trying to do? Are you trying to detect the presence or absence of light, or the reflectivity of some surface? I …

Color sensors and their applications based on real-time ...

· Partial color detection. In the color sensor, the main point is how to detect a color. We know that there is a disparity between the real color of the object surface and the acquisition image color by imaging device. This is a partial color, which is caused by the surrounding environment, such as light and noise. And the degree of color cast has a deal with the color temperature of the outside ...

Detecting obstacle with IR Sensor and Arduino

· The IR transmitter sends an infrared signal that, in case of a reflecting surface ( white color), bounces off in some directions including that of the IR receiver that captures the signal detecting the object. When the surface is absorbent ( black color) the IR signal isn’t reflected and the object cannot be detected by the sensor.

Arduino Paper Currency Counter using IR and Color Sensor

· In this structure, a colour sensor and an IR sensor are fixed with the cardboard like shown in the image below. Here the IR sensor is used to sense the presence of currency inside the slot and if there is a note, then the colour sensor will detect the color of the Note and send the color value to Arduino. And Arduino further calculates the currency value based on the color of the note. Code ...
