Waveshare Infrared Reflective Sensor
The reflective module with IR sensor is equipped with digital and analogue output. It works with a voltage from 3 V to 5.3 V. It enables the detection of obstacles in the range from 0 to 30 mm.
An infrared sensor contains two parts: an infrared transmitter and an infrared receiver, the infrared transmitter consists of an infrared LED array as a luminophore and a PN junction made of a special material with high infrared radiation efficiency, which usually is GaAs. When a current injected into the PN junction by forward bias voltage, it can excite a source of infrared light with a center wavelength range of 830nm-950nm. The power of the infrared light excited is proportional to the current injected. However, in the case that the injected current excesses the maximum rating, the power of the infrared light may decline as the current increases. The infrared receiver is a semiconductor device for translating the infrared light signal into the electrical signal. And the core component of it is a PN junction made of a special material. Its PN junction has a different structure from the general purpose diode, enabling more infrared light to be received. As the
intensity of the infrared light enhances, more current can be generated.
