Not 8mm as advertised. Useless for my 3D printer because doesn’t detect anything at 8mm. ### ⭐⭐⭐⭐⭐ Als Sensor für Pipersberg Gaszähler nur zu empfehlen *by S***R on Reviewed in Germany on 1 February 2023* In der aktuellen Zeit ist es wichtig seine Kosten zu kennen, also was liegt näher als den Gaszähler digital zu machen um immer den aktuellen Verbrauch im Blick zu haben? Das geht mit diesem Sensor echt einfach, direkt an ein Node MCU gehängt, Tasmota eingespielt und den Sensor als Counter eingestellt. Die Positionierung erledigt ein Adapter, den man auf Thingiverse herunterladen und wenn man einen 3D-Drucker besitzt ausdrucken kann. Der Sensor erfasst die Umdrehungen des Zählers sauber und präzise womit der Blick auf den Zähler selbst zukünftig entfällt. Kurzum diese Sensor wir noch öfter bei mir zum Einsatz kommen: Wasserzähler digitalisieren, Belevelingsensor für den 3D Drucker und so weiter... --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/380592437-2pcs-lj12a3-4-z-ay-m12-approach-sensor-inductive-proximity](https://www.desertcart.vu/products/380592437-2pcs-lj12a3-4-z-ay-m12-approach-sensor-inductive-proximity) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
