Microduino-Light-D1

The product number of Microduino-Light-D1 is: MSDT41

Microduino-Light-D1 is a digital light sensor module, which can detect the light intensity. .

Introduction 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-D1 sensor pins PIN1: GND PIN2: VCC PIN3(IO1): SDA PIN4(IO2): SCL Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.

Development

Program Download

• Download and unzip the program File:Sensor-Light-D1 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 "TSL2561T_Test.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-D1 to interface I2C of Microduino-Sensorhub.

Result

• After download, open the serial monitor.
• The serial monitor will print out the configuration information of the sensor, and then display the current light intensity in cycle.

Application

It can be used to detect the environment light intensity, and also can be used in devices such as light-operated switch and so on.
