ControlBombaNode for Node-RED

Overview

The ControlBombaNode is a custom Node-RED node designed to manage and control a water pump based on various parameters such as pressure, water level, and user-defined modes (automatic or manual). This node is particularly useful for IoT projects where precise control and monitoring of water pumps are crucial.

Features

1. Automatic Mode: Controls the pump based on water pressure, adhering to maximum and minimum thresholds.
2. Manual Mode: Allows manual control over the pump.
3. Safety Checks: Includes checks for empty water levels, time limits for pump operation, and configurable reset functionality.
4. State Monitoring: Keeps track of the pump's operational time and other state variables, which are sent back as output for further use or logging.

Input Payload Description

The input payload to the node should include the following fields:

• presion: The current pressure (float).
• reset: Boolean to reset the internal state, if needed.
• estadoBomba: The actual current state of the pump (Boolean).
• vacio: Boolean indicating whether the water tank is empty.
• automatico: Boolean to set the system to automatic mode.
• manual: Boolean to enable manual mode.
• nivelVacio: Float value indicating the water level at which the pump should stop.
• nivelActual: Current water level (float).
• nivelReinicio: Float value indicating the water level needed to restart the pump.

Example Payload:

msg.payload = {
    presion: 2.5,
    reset: false,
    estadoBomba: true,
    vacio: false,
    automatico: true,
    manual: false,
    nivelVacio: 0.2,
    nivelActual: 0.5,
    nivelReinicio: 0.8
};
