If you're looking for an IR transmitter and receiver package, this item is the one. This item consists of a wireless remote control that acts as a IR transmitter and an IR receiver on a tiny board with female to female jumper wires. You can use it to control your Arduino/microcontroller-based robots within 8m without signal obstructions. There are also various libraries in Github that can help interface with IR sensors and this item particularly. Check out the sample library given below. 

• Transmission distance: up to 8m(depending on the surrounding environment, the sensitivity of the receiver, etc)
• Battery: CR2025 button battery
• Battery capacity: 160mAh
• Effective angle: 60°
• Sticking material: 0.125mmPET
• Effective life: 20,000 times
• Static current: 3uA - 5uA
• Dynamic current: 3mA - 5mA
