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.

FAQs
Can this RCBO be used for three-phase systems?
- No, this RCBO is designed for single-phase systems (1P+N) only.
How often should I test the RCBO?
- It is recommended to test the RCBO at least once a month using the test button.
What does the 30mA sensitivity mean?
- The RCBO will trip if it detects a residual current (earth leakage) of 30mA or higher, providing protection against electric shock.
Can I use this RCBO for outdoor installations?
- The RCBO has an IP20 rating, which means it is not suitable for outdoor use unless installed in a weatherproof enclosure.
What is the purpose of the Type C tripping curve?
- The Type C tripping curve ensures the RCBO can handle moderate inrush currents (e.g., from motors or fluorescent lighting) without nuisance tripping.
