How to Use
In the case of working with a MCU:
- VCC ↔ 2.5V ~ 5.0V
- GND ↔ power supply ground
- DOUT ↔ MCU.IO (digital output)
Need to measure the RPMs for a blower and didn't want to risk unbalancing it with magnets and Hall sensor. Also didn't want anything to get sucked in and make a mess. Settled on a Laser safely secured away from the blower and a sticky reflective target on the wheel. Works great. I initially bought 2 others on that "Jungle" website and both failed (laser never lit up and soldering was poor).
Besoin de mesurer les RPM d'un ventilateur et je ne voulais pas risquer de le déséquilibrer avec des aimants et un capteur Hall. Je ne voulais pas non plus que quoi que ce soit soit aspiré et fasse des dégâts. Installé sur un laser sécurisé en toute sécurité loin du ventilateur et une cible réfléchissante collante sur la roue. Fonctionne très bien. J'en ai d'abord acheté 2 autres sur ce site Web "Jungle" et les deux ont échoué (le laser ne s'est jamais allumé et la soudure était mauvaise).
Le capteur détectera une surface de couleur claire à 1,5 m. Les surfaces plus foncées sont détectées de plus près. Il dispose d'un voyant d'alimentation et d'une lumière détectée par objet, ce qui signifie qu'il peut être testé en mode autonome avec juste une connexion d'alimentation. Son en-tête à trois broches prend un câble servo standard. La documentation que vous pouvez télécharger est au mieux sommaire. La sortie numérique, broche 1, est élevée si rien n'est détecté et passe au niveau bas lors de la détection, mais vous ne le trouverez pas dans la documentation.
The lasers on these sensors put out a strong beam, but I'm not getting the range I hoped for - except when the interrupting object is quite reflective.
The sensor will detect a light coloured surface 1.5 m away. Darker surfaces are detected closer. It has a power light and an object detected light which means it can be tested in stand alone mode with just a power connection. Its three pin header takes a standard servo lead. The documentation you can download is sketchy at best. The digital output, pin 1, is high if nothing is detected and goes low on detection, but you won't find that out from the documentation.
