Microduino-Lightness The product number of Sensor-Light-A1 is: MSDT42 Sensor-Light-A1 is a photosensitive brightness detection sensor module. The light sensor transforms the light signal into electric signal with the photosensitive resistance. Its sensitive wavelength is near that of the visible light, including the infrared and the ultraviolet. Description of the Sensor Pin Pins of the sensor: PIN1: GND PIN2: VCC General signal pins: PIN3(IO1): digital/analog signal PIN4(IO2): NC(null) Special signal pins: If it is IIC: IO1/IO2 are respectively SDA/SCL. If it is soft serial port: IO1/IO2 are respectively tx/rx. Special to Sensor-Light-A1 sensor pins PIN1: GND PIN2: VCC PIN3(IO1): Analog signal input PIN4(IO2): NC Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub. Feature Resistance photosensitive element, with high sensitivity. Specification Sensor voltage 3.3V~5V working voltage Size of the sensor Size of the board: 23.5mm*13mm; 1.27mm-spacing 4Pin interface connected with sensorhub; CAD drawing of the sensor: File:Sensor CAD.zip Function description The sensor outputs the corresponding voltage according to the detected light intensity. Connection This sensor can be connected to the following interfaces of core: A0~A7 Document Schematic diagram: File:Sensor-Light-A1.Zip.pdf Main sensor: File:Sensor-Light-A1 datasheet.pdf Development Program Download Download and unzip the program File:Sensor-Light-A1 Test.zip Programming Follow the Software Getting Started Guide. Select the Board, Processor and Port. Click [File]->[Open], browse to the project program address, and click "Microduino_Light_A1.ino" to open the program. After confirming all these items are correct, click "→" to download the program to the development board. Hardware Setup Referring to the following diagram, connect the Sensor-Light_A1 to the analog port A0/A1 of Microduino-Sensorhub. Result After download, open the serial monitor. The value displayed on serial monitor reflects the current light intensity detected by the sensor. Application It can feel the intensity of light around us. It can be used to detect the light intensity, and control the indoor lighting and object shading and so on.
