Solar-Powered Ultrasonic Liquid Level Sensor
This solar-powered ultrasonic liquid level sensor adopts self-solar power supply with no grid connection needed. It realizes accurate real-time liquid level monitoring via non-contact ultrasonic detection. Weather-resistant and wiring-free, it suits outdoor scenarios for 24-hour unattended operation with low maintenance cost.
| Power Supply DC 5V |
| Gateway Operating Current < 150mA |
| Sensor Operating Current < 30mA |
| Operating Temperature -20°C ~ 70°C |
| Measuring Range 0.1 – 3.0m |
Product Details
Working Principle
The sensor uses ultrasonic echo reflection to measure liquid levels: it emits sound pulses, calculates the round-trip time to determine the liquid surface distance, and derives the level from the installation height. It runs on a rechargeable battery, with a solar panel automatically recharging it to ensure uninterrupted operation when power is low

Core Features
- Solar-Powered Continuous Operation: Eliminates frequent battery changes; solar recharging keeps the sensor running indefinitely in most outdoor conditions.
- High-Precision Non-Contact Measurement: ±1% accuracy, 0.1–2.0m range, avoiding contact with corrosive/foaming media.
- Smart Wireless Monitoring: Tuya-compatible APP for real-time tracking, high/low level alarms, and remote access via 2.4GHz Wi-Fi/LoRa.
- IP67 Waterproof & Low Power: Outdoor-ready design with low power draw for extended battery life between solar charges.

Application Scenarios
- Off-grid water tanks, agricultural irrigation systems, and remote reservoirs
- Residential rainwater harvesting and commercial liquid storage
- Industrial wastewater pits, environmental monitoring sites, and construction projects
- Any location without reliable wired power access, where solar energy ensures maintenance-free monitoring
