KY-008 37-1 Laser sensor module KY-008
Laser sens Laser emit
KY-008 is actually laser emitter.

The Laser KY-008 is particularly neat because it can be directly powered from an Arduino output pin as it only draws 30 mA from the processor that has outputs rated for 40 mA.

Hardware connections

You need only supply ground and power to this device.

  • pin S                Arduino output pin (in example pin is used) (or +5V for  laser
  • pin middel        not connected
  • pin -                GND

Ordered some additional KY-008 laser modules. In this (other) batch the connections where reversed. Module worked only when connecting - to +5V and S to GND.
