Smart Relay Switch Design
Table
| Property | Value/Specification |
|---|---|
| Supply Voltage | 5 V for the relay circuit (with a regulator providing 3.3 V for the ESP32) |
| WiFi Interface | Provided by the ESP32-WROOM-32 |
| Relay Specification | SRD-05VDC-SL-C – 5V electromechanical relay suitable for high current switching |
| Additional Components | Transistor driver (e.g., 2N2222), base resistor (~1 kΩ), flyback diode (e.g., 1N4007), decoupling capacitors (100 nF near IC and 10 µF bulk capacitor) |
