Specification:

  • Number of sensors: 8
  • Dimensions: 75 x 127 x 4 mm
  • Supply voltage: 5 V or 3.3 V
  • Consumption current: under 100 mA
  • Output signal: analog
  • Output voltage range: 0 V to supply voltage
  • The optimum distance for measurement: 3 mm
  • The maximum distance for measurement: 6 mm
  • Weight: about 3 g (without connectors)

 

The strap can be used in robots such as linefollower (positioning line). Has a built-in MOSFET transistor, providing disable sensors to save energy, or change the intensity of illumination of the infrared LEDs.

 

There are several method use of output signals, e.g.:

  • built-in microcontroller comparator or ADC to measure voltages
  • using the analog comparator and the reading of the measurements in digital form

 

The bar can be machined using the module of Arduinoby connecting the outputs of the sensors at the analog inputs.

 

If necessary, the module can be divided into two independently operating strap, as well as the picture below:

The division requires przylutowania only one supplied resistor.
