An Infrared detector is a detector that reacts to infrared (IR) radiation. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector.
Features:
- Voltage - Collector Emitter Breakdown (Max): 30 V
- Current - Collector (Ic) (Max): 20 mA
- Current - Dark (Id) (Max): 100 nA
- Wavelength: 940nm
- Mounting Type: Through Hole
- Orientation: Side View
- Operating Temperature: -25°C ~ 85°C (TA)

Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- wavelength
- The distance between repeating peaks of a wave, often used to describe the colour of light in nanometres. For visible lasers and LEDs, wavelength tells you the approximate colour, such as red, green or blue.
