ME201W Wireless Fluid Level Sensor: Remote Tank Monitor with 4.0m Range and App Control

The ME201W wireless fluid level sensor provides a practical solution for remotely monitoring water and oil tank levels, eliminating the need for manual checks. Operating via 2.4GHz WiFi and compatible with the Tuya SmartLife app for both Android and iOS, this sensor delivers readings from 0.1m to 4.0m with an accuracy of ±0.02m. Manufactured in Shaanxi, China, with support for custom OEM, ODM, OBM, and software reengineering, it is designed primarily for integration into home automation systems. Powered by a 100-240VAC to DC 5V supply and functional within temperatures from -20℃ to 70℃, it offers reliable performance for various domestic tank monitoring applications.

Features and Construction

The ME201W sensor combines wireless connectivity with precise measurement capabilities for straightforward tank management. Its construction and specifications are geared towards providing accurate, remote data access for homeowners and installers.

Material and Build

The sensor’s housing is made from PC (polycarbonate), a material chosen for its durability and ability to protect the internal electronics. This construction ensures the unit can withstand typical environmental conditions encountered in tank monitoring setups, particularly within the specified -20℃ to 70℃ operating range. The use of PC contributes to a robust enclosure suitable for the sensor's intended applications with water and oil.

Size and Practical Fit

The key measurement provided is the sensor's detection range of 0.1m to 4.0m, which defines its capability rather than its physical dimensions. This range allows it to monitor fluid levels in tanks up to 4 metres in depth with high precision (±0.02m). The product is supplied as a single unit (MOQ 1 piece), and it includes a power supply adapter for connection to standard 100-240VAC mains electricity, converting it to the required DC 5V for operation.

Uses and Placement

This sensor is designed for specific fluid monitoring scenarios within a home automation context. Its application dictates both its placement and the practical benefits it delivers.

Event or Professional Use

For installers or those requiring custom solutions, the manufacturer offers OEM, ODM, OBM, and software reengineering support. This makes the sensor adaptable for integration into broader monitoring systems or for professional installations where specific branding or software functionality is needed. Its precise accuracy and wireless design allow for efficient setup in residential or light commercial tank monitoring projects.

Everyday Home Use

In a typical home setting, the sensor is used to monitor levels in water storage tanks, heating oil tanks, or similar reservoirs. The Tuya SmartLife app enables users to check levels remotely from a smartphone or tablet, providing convenience and helping to prevent run-dry situations. The 2.4GHz WiFi connectivity ensures it can link to most home networks without specialised hardware.

Benefits and Buying Value

The value of this fluid level monitor lies in its remote functionality, accuracy, and integration potential. It addresses a specific need within home automation with clear, measurable specifications.

Reuse and Low Maintenance

As a wireless electronic sensor, it requires minimal physical maintenance beyond ensuring a stable power connection and a clear signal path for WiFi communication. The durable PC housing is designed for long-term use. Its remote monitoring capability reduces the frequency of physical inspections, saving time and effort in routine tank management.

Why Choose This Product

The ME201W sensor is a defined choice for users seeking a wireless, app-controlled solution for tank monitoring with verified accuracy (±0.02m) and a substantial 4.0m range. Its compatibility with a major smart home platform (Tuya) and both major mobile operating systems provides broad usability. The availability of customisation support from the manufacturer also adds value for specific project requirements, making it more than just an off-the-shelf consumer device.
