Tank Level Monitor ULS-03GW Indoor Household Alarm Wifi Ultrasonic Mobile Tuya Smart Life APP Liquid Level Sensor Oil Solid

Wi-Fi Ultrasonic Liquid & Solid Level Sensor
Smart Monitoring via Tuya / Smart Life App | Indoor Household Alarm
The ULS-03GW is a smart, Wi‑Fi enabled ultrasonic level sensor designed to give you peace of mind by monitoring your water tanks, fuel reservoirs, or even solid storage bins—right from your smartphone. Whether you need to know when your household water tank is running low, track oil levels in a basement tank, or monitor grain or feed levels, this compact sensor provides accurate, real‑time data without ever touching the contents.

Features

Key Features
📡 Ultrasonic, Non‑Contact Measurement
The sensor mounts above the tank and uses high‑frequency sound waves to measure the distance to the surface of the liquid or solid material. Because there’s no physical contact, it works reliably with water, oils, chemicals, grains, pellets, and powders—without corrosion or contamination.

📱 Real‑Time Monitoring via App
View current level data instantly from the Tuya or Smart Life app on your iOS or Android device. The clean dashboard shows the level as a percentage, distance in centimeters or inches, and a visual gauge for quick understanding.

⚠️ Intelligent Alarms & Notifications
Never run dry or overflow again. Set your own high and low level thresholds in the app. When the level crosses a limit, you’ll receive an instant push notification to your phone. Perfect for ensuring water supply for households, livestock, or critical equipment.

🧠 Smart Home Integration
Link the ULS-03GW with other Tuya‑compatible devices. For example:

Automatically start a water pump when the tank drops below 20%

Turn off a fill valve when the tank reaches 95%

Combine with a smart plug to alert you or cut power in case of abnormal readings
🏠 Designed for Indoor Household Use
Compact and lightweight, the sensor is intended for indoor installations such as:

Household water storage tanks

Fuel oil tanks (basement)

Grain or feed bins (utility rooms, garages)

Chemical or solution containers

The operating temperature range (-10°C to 70°C) covers most indoor environments.
🔧 Easy Setup
No complicated wiring or calibration is needed. Mount the sensor above the tank, connect it to your 2.4GHz Wi‑Fi network via the Tuya app, and set your tank dimensions. The sensor automatically calculates the level.

Applications
🚰 Household Water Tank
Keep track of your water reserve for daily use, gardening, or emergency storage. Set a low-level alert so you never run out unexpectedly.

🛢️ Fuel Oil Tank
Monitor heating oil or diesel levels in a basement or utility room. Receive an alert when it’s time to schedule a refill, preventing cold mornings or downtime.

🌾 Grain & Feed Storage
For small‑scale farms or hobbyists, track feed levels in bins. Know exactly when to order more without guesswork.

🧪 Chemical or Solution Tanks
For indoor industrial or maintenance use, monitor levels of non‑corrosive liquids safely without contact.

Applications
🏠 Main Water Line Control
Install it on your home’s main water shutoff valve. When you leave for vacation, simply close the valve from the app. Combine with a leak sensor to automatically shut off water at the first sign of a leak—preventing thousands of dollars in damage.

🌱 Garden & Lawn Irrigation
Automate your sprinkler system or drip irrigation. Set a schedule to water every morning, or use the timer function to run for 30 minutes and then auto‑close. No more forgetting to turn off the hose.

🔥 Gas Line Safety
For natural gas or propane lines, the controller provides a reliable way to remotely shut off gas in an emergency. Voice‑activated gas shutoff gives you extra control during stove or fireplace operation.

🛁 Pool & Spa Fill
Use the timer to automatically fill your pool or hot tub to the desired level without having to stand by the hose. The app lets you stop filling from anywhere.

🚜 Agricultural & Livestock
Control water supply for livestock troughs, greenhouses, or remote irrigation zones. Wi‑Fi coverage and easy scheduling reduce daily chores.
