AI Overview
For a simple Arduino-controlled laser, the most direct pick is a 5V / 650nm module like Laser module for Arduino ($6.07), which is designed as an easy drop-in for Arduino projects.
Laser diode modules (red 650nm)
- Laser Diode - 5mW 650nm Red (5mW, 650nm) ($11.60) — basic dot laser module.
- Line Laser Diode - 5mW 650nm Red (5mW, 650nm) ($17.46) — projects a line instead of a dot (alignment/leveling).
- Cross Laser Diode - 5mW 650nm Red (5mW, 650nm) ($17.46) — projects a crosshair pattern.
- TTL Laser Diode - 5mW 650nm Red - 50KHz Max (TTL modulation, up to 50kHz, 5mW 650nm) ($39.28) — best when you want fast on/off control from a microcontroller pin.
- 1mw Laser Diode (1mW, 2.6–5V input range) ($74.13) — broader input-voltage compatibility when you may use 3.3V or 5V logic/power.
Pair it with a receiver / sensor (tripwire-style projects)
- Laser Detector module ($3.95) — simple way to detect a laser spot/beam with Arduino.
- The Laser Photoelectric Switch GAB100M-AK-5V (5V) ($85.41) — emitter/receiver photoelectric switch for beam-break style detection.
Mounting / aiming
- Adjustable Laser Mounting Stand ($17.46) — helps precisely aim and secure laser modules.
If you meant “laser sensor” (distance measurement)
- TF03 (ToF) Laser Range Sensor (100m) (up to 100m) ($436.55)
- TF03 (ToF) Laser Range Sensor (180m) (up to 180m) ($528.66)
