This amazing gray scale sensor can accurately measure light intensity from black to white. A gray scale, also called black - and - white, consists of various gray shades, ranging from the darkest black to the brightest white. The Arduino gray scale sensor combines a photocell and an integrated white LED on - board, facing the front. The connected LED helps you compare and gives reflective feedback for analyzing gray scale light ranges. It accepts different colors but outputs only gray scale values. The new design features a top - notch connector that extends the sensor's lifespan, offers a better voltage range, and is super easy to use. This sensor is commonly used in automatic lamps. When there's insufficient light, it can trigger a relay to turn on the lamp and turn it off when sunlight returns. It can also be used in simple data transmission, like Morse code with a flashlight, and as a line - following sensor. Key features include a wide voltage range from 3.3V to 5V, a standard assembling structure with two 3mm holes at 5cm intervals, easily recognizable sensor interfaces ('A' for analog and 'D' for digital), icons for simple function illustration, a high - quality connector, and an immersion gold surface. Specifications are a supply voltage of 3.3V to 5V, an analog interface, and a size of 22x30mm (0.87 x 1.18 in). Included documents are the Wiki (Analog Grayscale Sensor V2) and schematics. The shipping list has one Analog Grayscale Sensor V2 and one analog cable.
Using this analog grayscale sensor is easy. First, connect it to your Arduino following the interface labels ('A' for analog). Make sure the supply voltage is between 3.3V and 5V. You can use it in automatic lamps by connecting it to a relay. When the light intensity drops, the sensor will detect it and trigger the relay to turn on the lamp. For data transmission, you can use a flashlight to send Morse code. As a line - following sensor, place it near the line you want to track. When using the sensor, avoid exposing it to extremely high or low temperatures. Also, don't touch the sensor with dirty hands as it may affect its performance. To maintain the sensor, keep it in a dry and clean place. If the connector gets dirty, you can use a soft brush to clean it gently.
