Thanks for sharing the schematic image. It looks like you're using a PC817A opto-coupler to provide isolation between the input signal and the output, similar to what we've described in the project. Here's how this design works in general:
  • R3 (1kΩ): This resistor limits the current flowing into the diode part of the opto-coupler.
  • D2 (1N4148): This diode can be used for reverse polarity protection or signal rectification.
  • U4 (PC817A): This is the opto-coupler; it isolates the input and output electrically.
  • R4 (6.8kΩ): This pull-up resistor allows the opto-coupler's transistor output to pull low when activated.
  • 3.3Vout: This is the output signal that would go to a microcontroller like the ESP8266 - 12F.
  • GND: Common ground reference for the circuit.
  • F & TCOM: These appear to be the connections to the AC signal or other inputs.
Would you like help integrating this into your project, or do you have questions about modifying or understanding any specific aspects?

To integrate the new schematic with the ESP826612FESP8266 - 12F into your project for monitoring water levels, follow these steps:
Connections and Integration
  1. Power Supply:
    • Ensure that the ESP8266 is powered with appropriate voltage, typically 3.3V. Use a suitable voltage regulator if necessary to derive this from your existing power source.
  2. Connecting to Opto-Coupler Output:
    • Connect the output of the optocoupler (U4U4) to one of the GPIO pins on the ESP8266.
    • Connect 3.3Vout from the opto-coupler circuit to an available GPIO pin on the ESP826612FESP8266 - 12F. Ensure this pin is configured as a digital input to detect HIGH/LOW levels indicating water presence.
  3. Ground Connection:
    • Connect the GND of the ESP8266 to the common ground of the circuit.
  4. Additional Components and Connections:
    • Consider adding a filter capacitor between VCC and GND near the ESP8266 to stabilize the power supply.
    • Optionally, integrate status LEDs on unused GPIO pins of the ESP8266 to indicate water level status visually.
Schematic and Component Adjustments
  • Update your schematic in Flux to reflect these connections.
  • Make sure that the ESP8266 is included in the schematic with proper pin assignments.
  • Adjust component designators as needed based on your schematic naming conventions.
Code/Software
  • In the ESP8266 software, write code to read the GPIO pin connected to the opto-coupler output.
  • Implement logic to process the water level signal and take appropriate actions, such as sending alerts, notifications, or logging results.
Would you like assistance with the ESP8266 code or any other particular area?

create a 3.3 v regulated power supply from 12v 0v transformer

@copilot create a 3.3 v regulated power supply from 12v 0v transformer
1y
To create a 3.3V regulated power supply from a 12V AC transformer, you'll need the following components:
  1. Bridge Rectifier: To convert AC to DC.
  2. Smoothing Capacitor: To smooth out the rectified DC voltage.
  3. Voltage Regulator: A device like the LM1117-3.3 regulator can bring the voltage down to 3.3V.
  4. Decoupling Capacitors: To stabilize the output voltage from the regulator.
Here’s a step-by-step guide to design your power supply:
1. Bridge Rectifier
  • Use a bridge rectifier consisting of four diodes (1N4001 are common for this purpose) to convert the AC voltage to a DC voltage.
2. Smoothing Capacitor
  • After the bridge rectifier, add a large smoothing capacitor (e.g., 1000µF, 25V). This will smooth the pulsating DC voltage.
3. Voltage Regulator
  • Use an LM1117-3.3 voltage regulator for stabilization. This regulator will take the smoothed DC voltage and produce a stable 3.3V output.
4. Decoupling Capacitors
  • Place a 10µF capacitor on the input and output of the LM1117-3.3 voltage regulator to further stabilize the voltage.
Connection Instructions
  1. Connect the AC input to the bridge rectifier.
  2. Connect the positive output of the rectifier to the positive terminal of the smoothing capacitor, and connect the negative output to the ground.
  3. Connect the positive terminal of the smoothing capacitor to the input pin of the LM1117-3.3 voltage regulator.
  4. Connect the ground terminal of the smoothing capacitor to the ground pin of the regulator.
  5. Connect the 10µF capacitors between input/output and ground, respectively.
  6. Take your 3.3V output from the output pin of the regulator.
Here's a simplified connection format:
  • Connect AC to the Bridge Rectifier.
  • Connect Bridge Rectifier Positive to Smoothing Capacitor Positive.
  • Connect Smoothing Capacitor Positive to LM1117-3.3 Input.
  • Connect LM1117-3.3 Output to Load (where you need 3.3V).
  • Connect a Decoupling Capacitor between LM1117-3.3 Input/Output and GND.

which bridge is better 1n4001 or 1n4007
1y
Both the 1N4001 and 1N4007 are part of the 1N400x series of rectifier diodes, which are typically used for rectifying AC to DC in power supply applications. The main difference between them is their maximum reverse voltage (also known as Peak Inverse Voltage, PIV) rating:
  • 1N4001: Has a maximum reverse voltage rating of 50V.
  • 1N4007: Has a maximum reverse voltage rating of 1000V.
Recommendations:
  • For your application: Since you're working with a 12V AC transformer, both diodes can technically handle this voltage comfortably, but the 1N4007 would provide more headroom in terms of voltage safety. It offers a higher PIV rating, which may be beneficial if you're looking for more reliability or future-proofing the design against potential voltage spikes.
  • Conclusion: The 1N4007 is generally a safer choice due to its higher voltage rating, and it can be used in a wider range of applications beyond just your current project. Therefore, if you have both options and there's no significant cost difference, I recommend using the 1N4007.
