Review: Works perfectly - Our swimming pool does not have auto-fill and I can't see the water level from the house. There have been times when the level got dangerously low, almost to the point the circulation pumps could cavitate. I rigged up a stand using 1 1/4" PVC pipe on the tanning deck with the sensor attached to a angle brace. The very first day I set it up, the pool tech didn't tighten down a strainer basket lid and when the pump came on, water began spilling out to the point the pool lost 3" of water in 6 hours. I came home to the sound of the alarm and with the light elevated on the pole I could see blinking light from the house. another hour or so and I would have a burned up pump. First day-first save. Review: Works Like I Hoped It Would - We have the the "high water" sensor in a waste water tank at work. Now, we don't have to get on ladder to see if it's time to call to have the water removed. I was pleasantly surprised the first time it lit up. (Not using the "low water" sensor.) ## Features - 【INDOOR AND OUTDOOR WATER LEVEL ALARM】- IP55 rainproof and dustproof design, with high conversion solar panel, built-in rechargeable lithium battery, can charge the battery through solar energy, so there is no need to replace the battery. It can also be placed indoors. The product comes standard with a USB DC charging cable, which can be plugged in and used indoors.

First day-first save. ### ⭐⭐⭐⭐ Works Like I Hoped It Would *by C***S on February 17, 2023* We have the the "high water" sensor in a waste water tank at work. Now, we don't have to get on ladder to see if it's time to call to have the water removed. I was pleasantly surprised the first time it lit up. (Not using the "low water" sensor.) ### ⭐⭐⭐⭐⭐ Good for basic water level monitoring *by K***J on August 28, 2022* This product was purchased to monitor the level of a swimming pool after being winterized and a cover installed. The alarm can be silenced and only the flashing lights will alert, or the audible alarm can be set to various volume levels to be used along with the flashing lights. There are two sensors permanently attached. One alarms for a high level and the other for a low level. The permanent battery can be charged using the integrated solar panel or the included cord can be plugged in to a USB phone charger for ac operation. I have recently received this product so I can't speak for the longevity but this item performs as described with a good price point. ## Frequently Bought Together - Solar Water Level Sensor, High/Low Water Level Alarm with Dual Probe, 129 dB Red Strobe Siren with Adjustable Volume, Bobber Water Detector, 16.4ft Detect Cord, IP55 Waterproof for Indoor /Outdoor - Float Switch Pipe Mounting Bracket (Quantity 1) - Risinglink Smart Water Level Monitor, WiFi-Enabled, Text/Email Alerts, Indoor/Outdoor Detector, Battery Powered, Stainless Steel Float Sensor --- ## 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.co.uk/products/455102402-solar-water-level-sensor-high-low-water-level-alarm-dual](https://www.desertcart.co.uk/products/455102402-solar-water-level-sensor-high-low-water-level-alarm-dual) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-04*
