Contains a laser LED with a cylindrical heatsink and passive components that roughly provide the LED operating mode. The laser module KY-008 creates a small spot of light on the opposite object due to the special properties of the laser light. The beam is visible in a smoky or dusty environment. Focuses to a point.
The laser module (red) is used as an emitting component in a photo relay, in which the distance between the light source and the photo detectors is measured in meters. This arrangement of photographic devices is used when counting large objects that have moved between the source and the receiver. In security systems, this is called a light barrier. Other applications include a laser pointer, lighting effect rigs where a light spot is moved with a mirror.

Application features:
The KY-008 laser module is afraid of static electricity. Even an impulse excess of the supply or control voltage leads to damage to the LED. During operation, the LED heats up, which slightly reduces the heat sink on the LED. The main parameter of the laser LED power supply is current, not voltage. When heated, the resistance of the LED decreases, the current consumption increases, as a result, heating is accelerated and the developing process leads to negative consequences. In most cases, it is not required to operate the KY-008 laser module at maximum power. The current consumption can be reduced by sequentially installing a 22-100 Ohm resistor in the power supply circuit.
Consumption of maximum current causes rapid overheating, operation at half consumption mode slows down the self-heating process, but it will still occur. The most correct way to ensure reliable operation is to use a stabilizer or current limiter to power the KY-008 laser module.
