Infrared Reflectance Sensor Array: fail-safe sensitivity, maximum energy savings
This Infrared Reflectance Sensor Array’s two main qualities?
First, its acuity, which is enhanced by its digital I/O-measurable output (more sensitive than an analogue output with voltage divider bridge). Then its lower energy consumption, thanks to its 8 pairs of infrared transmitters and sensors arranged in series and spaced at a maximum distance of 9.5 mm (effectively halving the sensor’s consumption).
It is also an extremely lightweight module, since it weighs barely more than 3 g. The MOSFET transistor equipping this sensor module can disable its infrared LEDs according to its needs, hence reducing its energy consumption accordingly at times when your project doesn’t require use of the sensor, or when it requires use of an infrared sensor alone.
Uses of the QTR-8RC Infrared Reflectance Sensor Array
This QTR-8RC Infrared Reflectance Sensor Array is used mainly as a line sensor, making it the ideal module for a line-following robot. But it can also be used to detect objects, or even reflective surfaces. Note also that, depending on your project, it is possible to split this array of 8 sensors to obtain 6 sensors on the one hand and 2 on the other.
