ESP32-Controlled Smart Lighting System with Power Monitoring
This circuit appears to be a multi-channel current monitoring system using several ACS712 current sensors to measure the current through different loads, likely bulbs connected to a 220V power source. The current readings from the sensors are digitized by an Adafruit ADS1115 16-bit ADC, which interfaces with an ESP32 microcontroller via I2C communication for further processing or telemetry. A buck converter is used to step down the voltage to power the ESP32 and the sensors, and the system is powered through a 2.1mm DC barrel jack, indicating it is designed for external power supply.

Troubleshooting and FAQs
Common Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| RCBO does not trip when the test button is pressed | Faulty RCBO or improper wiring | Verify wiring connections and replace the RCBO if necessary. |
| RCBO trips frequently without load | Earth leakage or faulty wiring in the circuit | Inspect the circuit for insulation damage or loose connections. |
| RCBO trips under normal load conditions | Overcurrent or incorrect load rating | Ensure the load does not exceed 25A and check for short circuits. |

FAQs
Can the RCBO be used in outdoor installations?
- No, the RCBO has an IP20 rating and is not suitable for outdoor use. It must be installed in a protected enclosure.
What is the purpose of the test button?
- The test button simulates a fault condition to verify the RCBO's functionality. It should be tested periodically.
Can this RCBO protect against lightning strikes?
- No, the RCBO is not designed for surge protection. Use a surge protection device (SPD) for lightning protection.
What is the difference between Type C and Type B tripping curves?
- Type C RCBOs are designed for circuits with moderate inrush currents (e.g., lighting or small motors), while Type B is for purely resistive loads.
