Light slot Sensor Modules - for Car Kit

Two light slot sensor modules for the DIY car kits. With these modules the speed of the wheels can be measured.

These light sensors have a small piece in which the light is sent to a phototransistor. The phototransistor then responds to this when the light is transmitted. This means that this module can detect whether there is something in the light barrier or not. The type of light is infrared, so it does not react to visible light.

Specifications:

• Supply voltage: 5V DC
• Signal voltage: 5V
• Current (max): 20mA (largely the consumption of the LED)

Pinout:

• 5V (5V/plus)
• GND (earth/min/ground)
• OUT (indicates whether the light barrier is open or closed)

Package contents:

• 2x Light slot sensor module
• 2x Grooved disc
• 1x Dupont jumper wires
• 4x M3 bolt 10mm
• 4x M3 nut
