Infrared Reflective Sensor Array (8 Sensors)

Technical specifications

• Supply voltage: 3.3 V or 5 V (for 3.3 V stick the bottom left pad of the plate)
• Consumption: 120 - 150 mA
• Analog output
• 8 QRE1113 sensors

This product is a module with 8 analogue infrared sensors useful for building your own line follower. Infrared sensors are based on the radiation property of this wavelength, ie the white areas reflect the received IR radiation, and the black surfaces absorb the received IR radiation.

The module uses SMD, small and high quality QRE1113 sensors. These components incorporate an IR transmitter LED, as well as a phototransistor that changes its dynamic resistance according to the amount of IR radiation received in the same capsule.
