Power net portal is a special schematic object used to define a power or ground net. Power ports allow you to conveniently indicate a power net at any location in the design. Power nets of the same designator automatically connect throughout your design #portal #power
A generic fixed inductor for rapid developing circuit topology. *You can now change the footprint and 3D model at the top level anytime you want. This is the power of #generics
Below is a summary recommendation for your schematic. Note that within Flux you’ll need to add these components to your schematic and wire them together according to the following guidelines:
Connect the battery pack’s positive output to the VIN (or appropriate power input) of the NodeMCU and the motor driver’s power input.
Ensure all grounds (from the battery pack, NodeMCU, motor driver, and sensor) are tied together using the Ground component.
Water Level Sensor:
Connect the sensor’s output to one of the NodeMCU’s GPIO pins (or analog input if available).
Wire the sensor’s VCC and GND to the battery pack or regulated voltage as per sensor specifications.
Motor Driver Connection:
Wire the control inputs of the chosen motor driver (L298N or L293D) to suitable GPIO pins on the NodeMCU.
Connect the motor driver’s output to the water pump motor.
Ensure the motor driver’s VCC is supplied appropriately (this may be the same battery pack or a separate regulator if needed).
Control Strategy:
Program the NodeMCU so that when the water level sensor detects a specific level, it sends a control signal to the motor driver, thereby turning on the water pump motor.
Interconnections:
Use wires (and optionally a breadboard for prototyping) to make the connections.
Verify that the voltage ratings and current requirements of each component correspond to your chosen battery pack voltage (5V or 12V).
Before advising further, I have a quick clarifying question:
Which motor driver do you prefer for your design: L298N or L293D?
Feel free to answer or provide more details if needed, and I can help refine the schematic suggestions further.
Connect the battery pack’s positive terminal to the power inputs of both the NodeMCU ESP8266 (ensuring proper voltage regulation, if needed) and the L298N Motor Driver.
Tie together all ground connections (battery pack, NodeMCU, L298N, and sensor) using the Ground component.
Water Level Sensor:
Connect the sensor’s VCC and GND to the battery pack (or a regulated voltage according to the sensor's specifications).
Wire the sensor’s output to a GPIO (or analog) pin on the NodeMCU ESP8266.
L298N Motor Driver & Water Pump Motor:
Connect the NodeMCU’s GPIO pins to the control inputs of the L298N Motor Driver to manage the motor direction and speed.
Connect the output channels of the L298N to the Water Pump Motor.
Ensure that the L298N receives proper logic power (which might be supplied by the NodeMCU or a separate regulator) in addition to the battery pack's supply to power the motor.
Control Logic:
Program the NodeMCU to read the water level sensor. When a threshold is reached, it should trigger the L298N to drive the water pump motor.
Verify the battery pack voltage (5V or 12V) is compatible with all components or use appropriate voltage regulators where needed.
Interconnections:
Use wires and, optionally, a breadboard for prototyping, ensuring secure and reliable connections.
You can now use these guidelines to update your schematic in Flux. Let me know if you need help connecting specific pins or have further requirements!
Below is a summary of the circuit connections for linking the water level sensor to the NodeMCU ESP8266. You can use these guidelines in Flux’s schematic editor to create your design.
Important: Flux does not support importing a complete drawn circuit diagram. Instead, you can add the sensor and NodeMCU components and wire them as described below.

VCC
Connect to regulated supply (e.g., 3.3V)
NodeMCU 3.3V or external regulated supply
Ensure the sensor’s operating voltage matches
GND
Connect to common ground
NodeMCU GND and Battery Pack negative

You may also add a voltage divider if needed based on sensor output range
This wiring summary represents the circuit diagram for the water level sensor connection. In your Flux project, add the Water Level Sensor and the NodeMCU ESP8266, then use wires to connect:
VCC: From the sensor to the 3.3V supply (or a regulated voltage compatible with the sensor).
GND: From the sensor to the common ground (using the Ground component), which is also tied to NodeMCU GND.
Output: From the sensor’s analog output to NodeMCU’s A0 pin.
Feel free to use this wiring guideline within Flux’s schematic editor for your design. Let me know if you need further assistance or additional connection details!
