Liquid Level Control Pack with Shelly 1 Gen3

Liquid Level Control Pack with Shelly 1 Gen3: Tank Automation and Safety

The Liquid Level Control Pack from ShellyMadrid is the definitive technical solution for automated management of tanks, wells, or pools. This kit allows for external water presence detection and activation of power devices such as pumps or solenoid valves. It is the ideal tool for preventing overflows, automating filling, or protecting motors against dry running.

System Components

Shelly 1 Gen3: Advanced Power Control

The Shelly 1 Gen3 acts as the brain of the pack. Thanks to its ESP-Shelly-C38F processor with 8MB of memory, it guarantees immediate response and superior stability in critical environments. Its dry contact (potential-free) output allows it to control loads of up to 16A, enabling water pump control with complete electrical safety.

Shelly Plus Add-on: Data Interface

The Shelly Plus Add-on attaches directly to the main device to provide an isolated digital input. This component is responsible for reading the signal from the level sensor and transmitting it to the Shelly 1 Gen3, allowing the system to make intelligent decisions based on the actual liquid status without the need for complex wiring.

XKC-Y25 Liquid Level Sensor. Capacitive Level Sensor

This high-tech sensor allows liquids to be detected without direct contact. As a capacitive sensor, it is installed on the outside of the container, which prevents corrosion, chemical wear, and fluid contamination, drastically extending the lifespan of the entire installation.

Compatibility and Technical Specifications

It is important to note that, to ensure optimal operation, the capacitive sensor must be installed in non-metallic containers (such as plastic, polyethylene, glass, or ceramic). The sensor is capable of detecting liquid through walls up to 12-20mm thick. In metal tanks, the signal would be blocked, so this pack is specifically designed for polymer or glass material tanks.

Automation and Remote Control

From the Shelly Smart Control App, you can configure automatic scenes to stop your pump when the tank is full or activate it when the level is low. The system is fully compatible with Amazon Alexa, Google Home, and Home Assistant, allowing monitoring from anywhere in the world via Wi-Fi, without the need for additional hubs.
