Laser Receiver Module LASER lights have many applications like in counting, time measurement, laser guidance systems etc. It is very vital to correctly read and perform the corresponding function given in your code as any misread or malfunction in system can lead to fatal errors and losses to company. To keep this error in check this Non- Modulator Tube LASER Receiver sensor module is there to help you read the incoming laser signals accurately. It gives output of laser receiver in digital format and output pin is high when LASER is detected and low when LASER is not detected. This module works on 5V Voltage input and due to its small size you can use it in portable devices and industrial equipment. This Laser Receiver Sensor Module Laser output High Level is a sensor for Raspberry Pi and Arduino to receive the laser output and decode it digital data. At Input, the module Receives a laser signal when output high level; Does not receive a laser signal when output low level. On detecting a laser signal, output goes at a high level (5V) until the laser signal is there.

Witty Fox - OPT3001 Digital Ambient Light Sensor OPT3001 Digital Ambient Light Sensor is a single-chip lux meter that measures the intensity of light as visible by the human eye. Measurements can be made from 0.01 lux up to 83k lux without manually selecting full-scale ranges by using the built-in, full-scale setting feature. This capability allows light measurement over a 23-bit effective dynamic range. The OPT3001 is a sensor that measures the intensity of visible light. The spectral response of the sensor tightly matches the photopic response of the human eye and includes significant infrared rejection. The precision spectral response and strong IR rejection of the device enable the OPT3001 Light Sensor to accurately meter the intensity of light as seen by the human eye regardless of the light source. The strong IR rejection also aids in maintaining high accuracy when the industrial design calls for mounting the sensor under dark glass for aesthetics. The OPT3001 is designed for systems that create light-based experiences for humans and is an ideal preferred replacement for photodiodes, photoresistors, or other ambient light sensors with less human eye matching and IR rejection.

5mm LDR (Light Dependent Resistor) A 5mm LDR photoresistor sensor is made of a high resistance semiconductor. If light falling on the device is of high enough frequency, photons absorbed by the semiconductor give the bound electron enough energy to jump into the conduction band. The resulting free electron (and its hole partner) conduct electricity, thereby lowering resistance. A photoelectric device can be either intrinsic or extrinsic. An intrinsic semiconductor has its own charge carriers and is not an efficient semiconductor, for example, silicon. In intrinsic devices, the only available electrons are in the valence band, and hence the photon must have enough energy to excite the electron across the entire bandgap. Extrinsic devices have impurities, also called dopants, added whose ground state energy is closer to the conduction band; since the electrons do not have as far to jump, lower energy photons (that is, longer wavelengths and lower frequencies) are sufficient to trigger the device. If a sample of silicon has some of its atoms replaced by phosphorus atoms (impurities), there will be extra electrons available for conduction. This is an example of an extrinsic semiconductor. Photoresistors are basically photocells. Sensitivity The sensitivity of a photodetector is the relationship between the light falling on the device and the resulting output signal. In the case of a photocell, one is dealing with the relationship between the incident light and the corresponding resistance of the cell.

Colour Sensor A colour sensor is a device that detects and measures an object's or surface's colour. Color sensors measure the amount of light reflected or transmitted by an object in various wavelength bands. RGB (red, green, blue) sensors detect the intensity of light in the red, green, and blue areas of the spectrum, whereas CMYK (cyan, magenta, yellow, black) sensors measure the intensity of light in the cyan, magenta, yellow, and black regions of the spectrum. White light is a mixture of three basic colors known as primary colors. They are red, blue and green. These colors have different wavelengths. Combinations of these colors at different proportions create different types of colors. When the white light falls on any surface, some of the wavelengths of the light are absorbed by the surface while some are reflected back based on the properties of the surface material. Colour of the material is detected when these reflected wavelengths fall on the human eye. A material reflecting wavelengths of red light appears as red. The component used to detect colors is the Color sensor. What is a Color Sensor? A color sensor detects the color of the material. This sensor usually detects color in RBG scale. This sensor can categorize the color as red, blue or green. These sensors are also equipped with filters to reject the unwanted IR light and UV light.  Working Principle of Color Sensor To detect the color of material three main types of equipment are required. A light source to illuminate the material surface, a surface whose color has to be detected and the receivers which can measure the reflected wavelengths. Colour sensors contain a white light emitter to illuminate the surface. Three filters with wavelength sensitivities at 580nm, 540nm, 450nm to measure the wavelengths of red, green and blue colors respectively. Applications: Ensures accurate color in printing and packaging processes. Checks color consistency in food to maintain product quality. Matches colors in fabric and yarn production. Adjusts colors in cameras and displays for better images. Helps robots recognize objects based on color for automation. Matches colors in fabric and yarn production.
