The MORAYELEC ME201RSP is a solar-powered, wireless ultrasonic level sensor designed for remote water tank monitoring. It transmits level and temperature data via RF433MHz to a Wi-Fi gateway for integration into home automation, agricultural, or industrial control systems.

Features

  • Solar-powered operation with 6V/450mA panel for continuous, maintenance-free monitoring.
  • Wireless RF433MHz communication (up to 300m line-of-sight) to a 2.4GHz Wi-Fi gateway.
  • Ultrasonic level measurement from 0.1m to 4.0m with ±0.02m accuracy.
  • IP65-rated waterproof and dustproof housing for reliable outdoor installation.
  • Integrated temperature sensor and LED status indicators for system diagnostics.

Description

The ME201RSP utilizes an ultrasonic time-of-flight principle to measure the distance to a liquid surface, converting this to a precise level reading. Its solar panel and efficient power management ensure autonomous operation in remote locations without the need for wired power or frequent battery changes.

The system operates on a dual-network architecture: the sensor node communicates via robust RF433MHz to a local gateway, which then connects to a user’s network via 2.4GHz Wi-Fi for cloud or local server data access. The IP65-rated enclosure protects the internal electronics from dust and water jets, making it suitable for outdoor tank installations across a wide operating temperature range.

Key Features

  • Solar-Powered Autonomy: Integrated 6V, 450mA (1.5W) solar panel with Type-C backup charging ensures uninterrupted, off-grid operation.
  • Long-Range Wireless Network: RF433MHz link provides up to 300m (open field) communication from sensor to gateway, bridging to the internet via the gateway's Wi-Fi.
  • High-Precision Ultrasonic Ranging: Accurately measures liquid levels from 0.1m to 4.0m with a resolution of ±0.02m.
  • Rugged Environmental Protection: IP65-rated housing defends against dust and low-pressure water jets for reliable performance in harsh outdoor conditions.
  • Low Power Design: Sensor consumes ≤100mA at 5V DC, optimized for solar charging and extended battery life.
  • Integrated Diagnostics: LED indicators provide visual feedback on RF communication status and sensor reporting activity.
  • Wide Temperature Operation: Functions reliably in ambient temperatures from -20°C to +70°C.
  • Complete Monitoring Solution: Provides both level and temperature data for comprehensive tank management.

Applications

  • Remote monitoring of residential rainwater harvesting or well water tanks.
  • Agricultural irrigation system reservoir level tracking and management.
  • Industrial chemical or process water tank level monitoring in off-grid locations.
  • Livestock watering trough level control and automation.
  • Environmental monitoring of stormwater or retention pond levels.

Frequently Asked Questions

What is the wireless range of the ME201RSP sensor?

The sensor communicates with its gateway using RF433MHz, which has a theoretical line-of-sight range of up to 300 meters in open areas without obstructions. The gateway then connects to your local network via 2.4GHz Wi-Fi, with a typical indoor range of up to 50 meters from your router.

Can this sensor work at night or on cloudy days?

Yes. The integrated solar panel charges an internal battery during daylight. The system is designed with low power consumption (≤100mA @ 5V) to operate continuously through nights and periods of low sunlight. A USB Type-C port (5V @ 1A) is also provided for backup charging.

How do I install and configure the ME201RSP system?

Mount the IP65-rated sensor unit above the liquid surface in your tank, ensuring a clear path for the ultrasonic signal. Position the solar panel for optimal sun exposure. The gateway must be placed within RF range of the sensor and within Wi-Fi range of your router. Configuration typically involves connecting the gateway to your Wi-Fi network via a companion mobile app.

What liquids can the ME201RSP sensor measure?

The sensor is designed for water-based liquids such as fresh water, rainwater, or treated wastewater. It is not recommended for use with highly corrosive chemicals, foaming liquids, or in environments with heavy steam, as these can interfere with ultrasonic measurement accuracy.
