Sensor-IR-Sensor

The product number of Sensor-IR Sensor is: MSDI21

Sensor-IR Sensor is infrared emission sensor module.

Instruction of 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-IR Sensor sensor pins PIN1: GND PIN2: VCC PIN3(IO1): Digital signal input（pwm） PIN4(IO2): NC Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.

Development

Preparation

• Confirm that you has set up the development environment of Microduino, otherwise please refer to : Microduino Getting started
• Core choose
  • 1.Adopt Microduino-CoreUSB or mCookie-CoreUSB as the core directly.
  • 2.Adopt Microduino-Core or Microduino-Core+, and you also need Microduino-USBTTL to download program.

Program

• Open the program "IRsendDemo" in the library.

• include <IRremote.h> Call the infrared library function.
• IRsend irsend; Define the infrared sending object.
• irsend.sendSony(0xa90, 12); Send the infrared coding.

Hardware Setup

• Stack all modules together, and connect the interface on the back of IR-transmitter and the digital port (D3) of Sensorhub with dupont line.

Microduino-Sensorhub

mCookie-Hub

• Connect Sensorhub with LED, and connect them to the computer with USB cable.
• Select the right board card and COM port, and download directly after compiling. You can refer toAVR Core: Getting Started

• Open Arduino IDE, choose File→Examples→Microcuino→Sensor_IRremote→IRsendDemo the sample program, select the right board card in Tools→Board, and then compile.
• After compiling, choose the right port in Tools→Serial Port of Arduino IDE, adn then download the program directly.
• After downloading, you can open the serial monitor, and you can see the LED on IR emitter module twinkles once after input any value to the control panel, saying the infrared signal has been sent.

Application

It can be used in infrared remote controller to control various household appliances. At first, you need to confirm the infrared signal type and the protocol format.
