The LASER-MODULE-2 is a compact 5V red dot laser module built around a 650nm laser diode housed in a Φ6mm × 10.5mm brass tube. It converts electrical energy into a coherent, high-intensity red beam through a semiconductor p-n junction, producing a continuous dot-shaped spot suitable for alignment, sensing, and positioning tasks. The module operates from a 5V DC supply and draws under 40mA, allowing direct connection to Arduino and other microcontroller boards without additional driver circuitry for basic on/off control.
With an output power of 5mW, it falls within the commonly used low-power class for educational and DIY applications. The rated operating temperature spans a wide -36°C to 65°C, and the diode lifetime is specified at more than 1000 hours. Typical uses include laser pointers, leveling tools, mini LCD projectors, laser monitors, anti-theft alarm systems, and short-range optical sensing. The compact tube format simplifies mounting in tight enclosures, and the two-wire lead configuration supports straightforward integration into existing circuits.

Laser tube module Application

  1. Laser pointers and presentation tools using a 5V laser module.
  2. Leveling and alignment instruments in construction and DIY work.
  3. Laser monitors and mini LCD projection setups.
  4. Anti-theft alarm systems and security beam barriers.
  5. Arduino and microcontroller projects requiring a 650nm laser diode for sensing or positioning.
