Product Description:
An IR Receiver LED is a device that detects infrared rays. It has a negative polarity, which means that its anode and cathode are connected to the ground and the supply voltage in reverse order. When the IR Receiver LED receives light, it allows current to pass through it. The current flow is directly proportional to the intensity of the light. This IR Receiver LED has a diameter of 5mm and a power dissipation (Pd) of 100mW.

How to Use 5mm 940nm Infrared Receiver LED IR Diode LED (Flame
To use this IR receiver LED, mount it on your PCB or breadboard with the 2.54mm spacing. Wire it in reverse bias by connecting the cathode (longer lead) through a suitable series resistor (e.g., 10kΩ) to your supply voltage (up to 5V) and tie the anode (shorter lead) to ground. Measure the photodiode current or voltage drop across the resistor to detect IR intensity or flame presence.
