Selected this one (model ZS12010-2) as it is stainless, claims plated contacts on the internal reed switches and is about the right size for my application. The black pair of wires correspond to the lower float. The red pair for upper float. Working well with 20 ft of wire from float to microcontroller. Too early to tell how it will hold up over time. A more detailed description can be found at the outpost4 dot org blog. ### ⭐⭐⭐⭐⭐ It will work. *by R***N on May 11, 2024* The item is fine. It will be used on a trout pond. --- ## 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.com.cy/products/357057081-aopin-water-level-sensor-switch-stainless-steel-liquid-level-sensor](https://www.desertcart.com.cy/products/357057081-aopin-water-level-sensor-switch-stainless-steel-liquid-level-sensor) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-05-06*
