03GP LoRa Ultrasonic Level Sensor System
The 03GP is a professional‑grade tank level monitoring system built on LoRa + WiFi technology. Unlike WiFi‑only sensors that struggle with distance and battery life, the 03GP separates the sensor and the gateway:
The ultrasonic sensor (powered by a massive 9000mAh rechargeable battery) mounts above your tank and transmits level data wirelessly via LoRa – up to 1‑2 km in open space.
The LoRa gateway receives the data, shows it on its built‑in LCD screen, and forwards it to the Tuya Smart / Smart Life app through your home WiFi.
This hybrid design gives you the best of both worlds: ultra‑low‑power, long‑range sensing and convenient cloud access. It’s ideal for farms, remote water tanks, oil depots, grain bins, and any location where running power or WiFi to the sensor is difficult.

Key Features
🔋 9000mAh Rechargeable Battery – 8 Months Runtime
The sensor contains a high‑capacity 9000mAh Li‑ion battery. A full charge provides up to 8 months of continuous operation. When it’s time to recharge, simply plug a standard USB cable (USB‑C) directly into the sensor’s charging port – no need to open the housing or remove the battery. For locations with a power outlet, you can also leave the sensor plugged in permanently.
📡 LoRa + WiFi Hybrid Architecture
Sensor → Gateway: LoRa (long range, low power, excellent wall penetration)
Gateway → Cloud: WiFi (2.4GHz, connects to your home router)
Local display: The gateway shows current level and distance – instant reading without a phone
🧠 Dual Monitoring – Gateway Screen & Mobile App
Check tank level at a glance on the gateway’s LCD (great for basements, workshops, pump houses)
Monitor remotely from anywhere via Tuya Smart or Smart Life app
Both sources update in real time – no delay, no guesswork
🌊 Non‑Contact Measurement – Liquids & Solids
Ultrasonic technology measures from above, never touching the material. Works perfectly with:
Water tanks (household, irrigation, livestock)
Fuel oil, diesel, or petrol tanks
Grain bins, feed silos, seed hoppers
Rainwater collection tanks, chemical totes (non‑corrosive)
⚠️ Smart Alerts & Automation
Set high and low level thresholds in the app
Receive instant push notifications when your tank is too low or about to overflow
Create automations with other Tuya devices: automatically start a pump, close a valve, or turn on an alarm
🏗️ Easy Installation – One Small Hole
Drill a 22 mm (7/8 inch) hole at the top of your tank
Insert the sensor, secure with the included gasket and lock nut – watertight seal guaranteed
Mount the gateway anywhere within LoRa range, plug it into power and WiFi, and you’re done
How It Works – Step by Step
Mount the sensor above your tank (0.1 – 3 m range). Use the supplied drilling template to make a 22 mm hole.
Power the sensor – it comes pre‑charged. For a full 8‑month run, simply install it. When the battery runs low, charge via the sensor’s USB‑C port (or leave it plugged in permanently if power is available).
Place the LoRa gateway within 1‑2 km (line‑of‑sight) of the sensor. Connect it to your 2.4GHz WiFi using the Tuya Smart app.
View your level – on the gateway’s LCD or on your phone. Set alerts, share access with family members, or integrate with pumps and valves.
