Moray ME201W Wireless Fluid Level Monitor: Remote Tank Sensing from 0.1m to 4.0m via Smartphone App

The Moray ME201W Wireless Mobile Application Detector is a specialised sensor designed for remote monitoring of liquid levels in tanks. Originating from Shaanxi, China, this device transmits data over a 2.4GHz Wi-Fi network to the Tuya SmartLife application, compatible with both Android and iOS operating systems. It provides a practical solution for home automation systems, allowing users to check water or fuel tank levels without manual inspection. The sensor operates effectively across a broad temperature spectrum from -20°C to 70°C, making it suitable for various installation environments. Powered by a standard 100-240VAC to DC 5V adapter, it offers a measuring range of 0.1 metres up to 4.0 metres with a stated accuracy of ±0.02 metres.

Features and Construction

The ME201W model combines wireless connectivity with precise measurement for tank management. Its construction and specifications are geared towards reliable, remote data acquisition for residential automation projects.

Material and Build

The device features a housing made from PC, or polycarbonate, a material chosen for its durability and rigidity to protect the internal electronic components. This construction provides a stable enclosure suitable for the sensor's operational environment. The brand, Moray, supports customisation services including OEM (Original Equipment Manufacturer), ODM (Original Design Manufacturer), OBM (Original Brand Manufacturer) and software reengineering, indicating a focus on adaptable solutions for different user or integrator needs.

Size and Practical Fit

While exact physical dimensions for the housing are not specified, the core functional specification is its fluid level measuring capability. The sensor accurately determines the distance to the liquid surface within a range of 0.1 metres to 4.0 metres. This 4-metre range accommodates a variety of tank depths commonly found in domestic settings. The ±0.02 metre accuracy provides a precise reading, enabling users to monitor tank contents effectively for planning refills or managing usage.

Uses and Placement

This sensor is designed for integration into systems where remote liquid level knowledge is valuable. Its application scope and connectivity make it relevant for both planned automation and straightforward monitoring tasks.

Event or Professional Use

For professional integrators or specific project requirements, the manufacturer's offer of custom OEM, ODM, OBM and software reengineering allows the ME201W to be tailored. This means the core technology can be incorporated into bespoke monitoring systems, branded differently, or have its software adapted for specific functionalities beyond the standard app. Its operation in temperatures from -20°C to 70°C supports use in controlled industrial environments or outdoor installations where seasonal temperature variation occurs.

Everyday Home Use

In a typical home automation context, the sensor is primarily intended for monitoring water tanks (like rainwater harvesting or well systems) or fuel oil tanks. The wireless setup eliminates the need for running data cables, simplifying installation. Users can check levels remotely via their smartphone, receiving alerts or viewing data through the Tuya SmartLife app interface. This provides convenience and helps in managing resources, preventing unexpected shortages.

Benefits and Buying Value

The value of the ME201W sensor lies in its specific combination of wireless operation, app integration, and measurement precision. It addresses a clear need for remote tank management.

Reuse and Low Maintenance

As a solid-state electronic device with a PC housing, it requires minimal routine maintenance beyond ensuring a stable power and Wi-Fi connection. Its design for continuous monitoring means it can be installed as a permanent fixture, providing ongoing data without recurring effort. The wide operating temperature range contributes to long-term reliability in non-extreme conditions.

Why Choose This Product

The Moray ME201W offers a defined solution for remote tank level monitoring with key differentiators: its 4-metre measuring range with ±0.02m accuracy, compatibility with the widely-used Tuya SmartLife ecosystem, and the option for customisation. Compared to manual dipsticks or wired gauges, it provides the convenience of remote access via a smartphone app. For buyers, it represents a specific tool for a specific task—automating the observation of liquid levels—backed by a measurable performance specification and standard smart home integration.
