Microduino-IR-receiver

The product number of Sensor-IR-receiver is: MSDI22

Sensor-IR-receiver is an infrared receiving sensor.

Sensor-IR-Receiver contains a semiconductor device, which can turn the infrared light signal into electrical signal. Its core part is a PN junction with special material. Compared with the ordinary diode, it adopts great change in structure with a larger infrared receiving area, which makes the current increase accordingly.

Introduction of Sensor Pins

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

Development

Preparation

• Make sure you build Microduino IDE or refer to: Microduino Getting started
• Core selection
  • 1. Adopt Microduino-CoreUSB or mCookie-CoreUSB as the core.
  • 2. Adopt Microduino-Core or Microduino-Core+ as the core plus Microduino-USBTTL as the program download module.

Program

• Open " IRrecvDemo " program in the libraries.

• include <IRremote.h> Use infrared library function
• int RECV_PIN = 10; Define infrared receiving pin as 10, which can also be changed by users according to personal needs. (For example: Change " RECV_PIN = 11" in the program examples to " RECV_PIN = 10")
• IRrecv irrecv(RECV_PIN); Define infrared receiving object
• irrecv.enableIRIn(); Start infrared receiving
• Receive and output

 if (irrecv.decode(&results)) {      
   Serial.println(results.value, HEX);
   irrecv.resume();
 }

Hardware Buildup

• Connect the interface on the back of the IR-receiver with D10 digital port of the Sensorhub;
• Please refer to: Microduino-Sensorhub

• Please refer to: mCookie-Hub

• Connect the core, Sensorhub and the IR-receiver to a computer with a USB cable.
• Select the right board and COM port, compile and download. You can refer to AVR Core：Getting started

• After download, you can open the serial monitor and use the infrared remote controller to send signals to the infrared receiving head. When you see the LED light on the IR-receiver blinks once, it means the receiving head has gotten the signals while the serial console will print decoded data.

Application

Microduino-IR-receiver can be used in infrared remote control, which is able to be matched with all kinds of infrared remote controller. You need to make sure the infrared signal type and protocol format before using.
