Tuya SmartLife Fluid Level Monitor Wireless Water and Fuel Tank Sensor with Remote Control via Mobile App for Home Automation Systems, PC Material, 0.1m to 4.0m Range, ±0.02m Accuracy
Tuya SmartLife Wireless Fluid Level Monitor for Remote Water and Fuel Tank Sensing

This wireless fluid level monitor provides a practical solution for remotely tracking the contents of domestic water or oil storage tanks. By connecting to the Tuya SmartLife mobile application via a 2.4GHz WIFI connection, it allows users to check levels and set alerts from their iOS or Android smartphones, integrating seamlessly into existing home automation systems. The device is designed for straightforward installation and offers reliable monitoring with a specified measuring range, removing the need for manual checks and providing greater oversight of household fuel and water resources. Its support for custom OEM, ODM, OBM, and software reengineering means it can be adapted to fit specific project requirements beyond standard home use.
Features and Construction

The monitor is built around core functionality for remote tank management, focusing on wireless connectivity and accurate measurement. Its construction and specifications are geared towards reliable performance in typical residential environments, with details provided for its operational limits and technical capabilities.
Material and Build
The primary housing material is listed as PC (Polycarbonate), which is used to encase the electronic components. This material provides a durable and rigid shell suitable for protecting the internal circuitry. The build is centred around enabling its primary function as a wireless sensor, with connectivity facilitated through its integrated WIFI module operating on the 2.4GHz frequency band for compatibility with standard home networks.
Size and Practical Fit
The key performance specification is its measuring range, which spans from 0.1 metres to 4.0 metres, with a stated accuracy of ±0.02 metres. This range makes it suitable for monitoring the fluid level in many common domestic tank sizes. The device itself is a compact sensor unit designed to be installed at the top of a tank, and its operational temperature range of -20°C to 70°C defines the environmental conditions in which it is designed to function correctly.
Uses and Placement

This monitor is designed for integration into automated home systems, specifically for managing water or fuel oil storage. Its application focuses on providing remote visibility and control, which is valuable for maintenance, planning, and avoiding shortages.
Event or Professional Use
While primarily aimed at home automation, the product's support for custom OEM, ODM, OBM, and software reengineering indicates its potential for professional or event-based applications. This flexibility allows the core technology to be adapted for specific commercial monitoring projects, specialised tank setups, or integrated into larger bespoke control systems where standard consumer products may not suffice.
Everyday Home Use
For daily residential use, the monitor connects to the Tuya SmartLife ecosystem, allowing homeowners to check their water tank or heating oil tank levels from anywhere via their phone. This can help in planning refills, detecting potential leaks through unexpected level drops, and providing peace of mind while away from the property. It eliminates the physical inspection of often awkwardly located tanks.
Benefits and Buying Value

The value of this device lies in its specific function of remote monitoring, its stated technical accuracy, and its integration capabilities. It addresses a clear need for visibility over stored resources without requiring manual intervention.
Reuse and Low Maintenance
As an electronic monitoring device, its value is in continuous reuse over time, providing ongoing data without consumable parts. Maintenance would primarily involve ensuring the power supply (100-240VAC to DC 5V) remains connected and the WIFI connection is stable. The PC housing material contributes to a robust build intended for long-term installation in the specified temperature range.
Why Choose This Product
This product is a suitable choice for someone needing a specific, app-connected solution for monitoring a water or fuel tank remotely. Its defined 4-metre range and ±0.02m accuracy provide concrete performance parameters. The integration with the widely used Tuya SmartLife app platform offers a familiar control interface for many smart home users, and the option for custom engineering provides a pathway for more specialised requirements beyond off-the-shelf use.
