1-channel relay module with 2x water level sensors 12V/250VAC 10A

The OKY3028 (XH-M203) is a fully automatic water level controller module. It is designed to reliably manage a connected pump or valve to maintain a consistent liquid level within a container.

Key Features
- Automated Pumping Control: When the liquid level falls below the lower sensor, the onboard relay closes to activate a pump or open a valve.
- Automatic Shut-off: Once the liquid reaches the upper sensor, the relay opens, deactivating the pump to prevent overflow.
- Sensor-Based Operation: The module functions using external water level sensors (probe-electrodes) for accurate detection. Please note: sensors are not included with this module.

Applications
This controller is well-suited for a range of automated water management projects. Common uses include maintaining levels in water towers, storage tanks, and ponds, as well as integration into water conservation systems.
