Laser module for Arduino 650nm 6mm 3V 5mW red

The laser module is an LED with a cylindrical copper heatsink for cooling, which is used as the emitted component. The module can be used both in a security system using an outgoing beam as an obstacle, upon crossing which an alarm is triggered, and in domestic projects.

The module board is designed based on the KY-008 laser diode and auxiliary passive elements, to ensure the stable operation of the laser. The advantages of the module are: consumption of 30 mA of current and the ability to consume power directly from the Arduino board. The module generates red radiation in the range of 650 nm with a constant power of 2 - 5 mW.

The light spot of the laser can extend to a distance of up to 14 meters. The radiation intensity of the KY-008 laser module is controlled by current. When the threshold value of the passing current is exceeded, the intensity of the radiation of the laser LED increases sharply, respectively, at low currents, the laser emits like a conventional LED.

The module is connected using a common I2C serial interface that works in conjunction with the Arduino Uno or other microcontrollers. Power is connected to the module from contacts +5V and GND. You can supply power to the module from an external power source or from the ports of the Arduino Uno. The S output serves as a contact for transmitting control signals to the microcontroller.

When working with the module, you must be careful not to direct it into the eyes, in addition, during long work, the laser heats up very much, especially at high intensity of the passing current.
