Frequently asked questions
Can I see the emitted light?
No. Near-infrared light is invisible to the eye, so you need a phone camera or an IR receiver to confirm the module is emitting.
How is it used in a project?
It is used as the emitter half of an infrared pair, with a receiver detecting the beam for obstacle or break-beam sensing. Check the module's voltage and current requirements before wiring.
