The IR Shield is designed for Arduino and includes an infrared transmission and reception module, various interfaces such as nRF24L01 and Xbee, a Micro SD slot as well as a temperature and humidity sensor. With this IR shield, you can automate your home by creating a DIY indoor temperature and humidity meter or a controller for infrared household appliances such as air conditioners and televisions.

Hardware Pin Mapping:

• D0: XBEE_TX
• D1: XBEE_RX
• D2: nRF24L01_IRQ & STD Button
• D3: IR_TX
• D4: SD_CS
• D5: IR_RX
• D6: LED1
• D7: LED2
• D8-D9: nRF24L01_CS
• D10: nRF24L01_CS
• D11: MOSI
• D12: MISO
• D13: SCK
• A0: A0 Button

Notes:

• IR_TX activates the infrared LED when D3 is set to high.
• IR_RX uses the HS0038B as the infrared receiving module.
• Jumpers can be directly connected to the Arduino IO. If not needed or the respective ports are occupied, you can remove them.
• Connect LED1 to D6. If the output is high, LED1 is activated.
• Connect LED2 to D7. If the output is high, LED2 is activated.
• Adjust the switch level according to the main Arduino board.
